This speculation ended in October with Tennant's announcement about his future on the series.

 * Late June - Several UK media reports indicated that David Tennant was in negotiations to return to Doctor Who for the 2010 series, but no official announcement was forthcoming (leading to additional speculation in the wake of the cliffhanger of The Stolen Earth a few weeks later), although it was known that he was to appear in the 2008 Christmas special as photos of him shooting the special had leaked to the press months earlier.
 * 26 June - WC: Who Ate All the Biscuits? (BBC Writers' Comics) was uploaded.

It was the last episode to be produced by Phil Collinson, the first of the revived series' original producers to depart. The episode featured the one-time returns of Noel Clarke, Camille Coduri and K9 to the series; Catherine Tate left the series as a regular with this episode. This was the last regular weekly episode of Doctor Who scheduled until Series 5 in 2010. Like the previous season finales, the broadcast of Journey's End sparked a frenzy of Internet discussion, both pro and con. The episode featured the greatest concentration of active companions (as opposed to illusions and images) in the series' history (not including the non-canonical Dimensions in Time). The episode was viewed by 10.57 million people and became the No. 1 program for the week -- the first time this had occurred for any episode in the forty-five-year history of Doctor Who -- despite competition from the Wimbledon finals; it also repeated the previous week's feat and scored an Appreciation Index figure of 91, again unheard of for both Doctor Who and for a mainstream television production.. The episode concluded with a teaser for the 2008 Christmas special, at the time of broadcast left untitled but later announced as The Next Doctor. As K9 did not appear in Series 2 of The Sarah Jane Adventures, this marked his final appearance until the post-season mini-episode From Raxacoricofallapatorius With Love aired in March 2009.

Julie Gardner confirmed in the article that Tennant had made his decision as to whether he would stay on for the 2010 season, but she confirmed he would appear in all of the special episodes scheduled for 2009. Despite this, wildcat Internet rumours persisted that Morrissey would replace Tennant as early as the 2008 Christmas special, while some UK media reported Tennant had signed an agreement to stay with the series through Series 5 in 2010.
 * 12 July - Doctor Who swept the television categories at the second annual Constellation Awards, a Canadian award presented as part of the Polaris science fiction convention. David Tennant won for best Male Performance in a Science Fiction Television episode for his work on the two-parter TV : Human Nature/The Family of Blood; Carey Mulligan won the female equivalent for Blink; and the series itself won for Best Science Fiction Television Series of 2007.

The issue also included a second surprise: when the polybag was removed, all text on the front cover (except around the UPC symbol) was revealed to be "BAD WOLF", including the title banner for the magazine itself. This was a tie-in with the ending of Turn Left.

Singer Tim Phillips, who performed "Song for Ten" in The Christmas Invasion, performed the extended version of the song introduced on the Series 1 & 2 soundtrack CD. Davros, the Graske and other monsters made cameo appearances as well. As a tribute to the BBC Radiophonic Workshop and Delia Derbyshire, Music of the Spheres ended with the original 1963 arrangement of the "Doctor Who theme".

Tennant made the announcement on live TV when he accepted the National Television Award for Outstanding Drama Performance. The series also won Most Popular Drama. Tennant's announcement was made hours after The Guardian broke the news first on its website. As the winner of the NTA was not previously known, it was uncertain whether Tennant would be able to deliver his announcement on the air. The announcement was timed to occur during an intermission in his performance of Hamlet, and Tennant pre-recorded a version of it in the event the live transmission broke down. Earlier in the day, Russell T Davies and Benjamin Cook appeared on a TV broadcast discussing their book, REF: Doctor Who: The Writer's Tale, and managed to avoid discussing the yet-to-be-made announcement. (REF: Doctor Who: The Writer's Tale - The Final Chapter)
 * 29 - Tennant's announcement sparked a period of intense fan and media speculation as to who would be chosen to portray the Eleventh Doctor.

Series 4 was released in Canada even though the CBC was only midway through its broadcast of the season.

 * 12 December - Journey's End was broadcast on the CBC in Canada, concluding its broadcasts of Series 4. The network chose to air an extensively edited version of the episode, cut down to approximately forty-four minutes to fit a standard sixty-minute time slot, with commercials, raising the ire of many Canadian fans who afterward flooded the CBC's website with complaints. The season ended with no plans by the CBC to broadcast Voyage of the Damned or The Next Doctor (the CBC ultimately lost the rights to air The Next Doctor and the remaining 2009 Specials, plus Series 5, in the spring of 2009).
 * 24 December - A little-known named Matt Smith attended a secret photo shoot; it was so secret, in fact, that the hairstylist and photographer were not informed what it was for. Later, an image of the TARDIS was digitally added to the photos, which were issued on 3 January 2009 to announce Smith as the actor to play the Eleventh Doctor.
 * 25 December - The Next Doctor, the fourth Doctor Who Christmas special, debuted on BBC One. This was considered the last episode of Series 4 before four special episodes planned over the next year in lieu of a full season of Doctor Who, which was scheduled to return to a full thirteen-week season in 2010. This was the first story since The Deadly Assassin in which the Doctor did not share an adventure with a clearly defined companion even in a one-off manner, as the story twisted conventions by placing the Doctor in the companion role. The title of the first special, Planet of the Dead, was unveiled during the closing credits. The episode was notable for including a sequence in which the nine actors who played the Doctor prior to Tennant were shown; in some cases, such as William Hartnell and Patrick Troughton, this marked the first on-screen appearance of their Doctors in more than two decades, and it was the first unambiguous confirmation that the revived series counted Paul McGann's Eighth Doctor in its continuity.
 * 25 - An edition of Doctor Who Confidential followed the broadcast.
 * 29 December - COMIC: Doctor Who Classics Volume 2, a graphic novel-style release reprinting issues of COMIC: Doctor Who Classics by IDW Publishing, was published.
