What's with all the "next movie will be 4th gen" talk? Yes, we're due--in fact, overdue--for a 4th gen critter. But Word of God hasn't even mentioned the 4th gen in passing, as far as the next movie goes. We might see one, we might not see one. It's not going to happen for sure.
ANYway, I don't think that the writers can get away with not having Arceus in this movie and skipping it in the anime. They've made such a valiant attempt to make it vaguely important that it needs to be somewhere. Our best bet is the movie, because we've seen bits and pieces of it in trailers (...that sounds gory). I hope it has more than a small role, because there's really no one else to give the spotlight other than people who've already had it.
