Honestly, don't bet on it, Jerry. It's for the annual Children In Need tv special they do every year. Every year the Doctor Who staff have given the show something to attract viewers. One year was the "Dimensions in Time" Doctors 4 - 7 teamup, another was the "Curse of the Fatal Death" parody with Rowan Atkinson, Hugh Grant, and other big name Brit stars playing The Doctor, and two years ago was a five-minute scene that took place immediately after Eccleston regenerated into Tennant, showcasing Tennant's Doc going through the post-regen trauma, and freaking Rose out. These mini-episodes are never included in the DVD sets or anything (save "Curse of the Fatal Death" which was released by itself for charity profit), as the Children In Need foundation owns them separately from the normal BBC produced episodes.

However, I'm really hoping they will make an exception for this and provide it with the DVD set of Season Four.

Meanwhile, however, I will be illegally downloading the SHIT out of this...
