In the Daft Dimension, three Doctor Who fans expressed their excitement for all of the new announcements that had recently been made, including one that involved an old Doctor. (COMIC: The Daft Dimension 579)

Behind the scenes
In a post-The Power of the Doctor context, the Doctor being referred to is clearly intended to be the Fourteenth Doctor as played by David Tennant. At the time of the strip's publication, it was only known that Tennant would be returning to the series in an unspecified capacity, with most naturally assuming that he would be playing, of course, the Tenth Doctor, hence his being referred to here as an "old Doctor".
