Prologue is clearly shown on the title card when you watch the webcast. The most recent Doctor Who Extra also has a title card of Prologue for the obvious reason that it is about the Prologue webcast. The only place where "New Series" comes into play is on the BBC website, but not the webcast itself. I believe Prologue is therefore the correct title.
