I'm excited this is on... but it does sound like it will mainly be a preview of the new contestants, with a couple of interviews from past contestants.
Call me choosy, but if they're going to have a show beforehand I'd rather see selected highlights from past seasons, since we're going to get plenty of footage from the new contestants once the series starts properly.
Still, I'm pleased we're getting an extra week of SCD. I just hope they find time to interview Matt, who is now the only one from series four who hasn't had some kind of exit interview.
