If the video advert on Amazon for it is anything to go by, it seems to be going to consist entirely of Gary and Mikey, with a bit of Daniella in there if we're lucky...
I wish the DVD included all the routines in full as a bonus. I'd definitely buy it then. It wouldn't be too hard to do - once you cut out all the filler, there's not that much actual skating left.
I bought the series 2 DVD 'back in the day' and overall I was pretty disappointed with it. The routines they had on there were not generally people's better routines. I hardly watched it & ended up selling it. I never bothered with any of the others.
In contrast I love the Tour DVDs and watch those regularly.
