I'm jumping into the discussion late, but I completely agree that it doesn't seem fair that some people are getting their old partners back and others aren't. If someone's truly an all-star, shouldn't he/she be able to dance well with someone other than his/her original teacher? Besides, it would just be fun to see what people could do with someone new.
I also sort of wish they had limited the cast to people who hadn't won before. There have been plenty of popular contestants who didn't win, haven't there? It just doesn't seem necessary to give someone who already has a mirror ball trophy a second chance to win another one when others have come so close and not made it--or perhaps lost it due to reasons that didn't have all that much to do with their dancing.
Count me in as one who never saw why Sabrina's ousting was such a huge shocker either. Yes, she was talented, and yes, other who weren't as talented outlasted her that season. But what season hasn't that happened? I didn't see her as ultimately winning the thing anyway, and the fact that we've had to hear about it every season since has made me less and less impressed with her. I hope it doesn't come down to Disney fans vs. gymnastic tweens in the voting this time out. I'd really like to see someone win for his/her dancing, but I'm afraid it's going to come down to huge fan base issues this time around even more than it usually is--complicated, of course, by the fan bases for some of the pros as well.
There are a lot of people I could live with winning this year, but there are certainly those I'd be happier with winning than others. And there are definitely some I'd not be upset to see gone quickly too.
