I think that Kyurem being in White 2 and vice versa is definite evidence for the cover pokemon being the Rom/Ram that N caught in White and Black 1. It makes the most sense in terms of not sticking to the rule established by the first two is having the legendaries on oppositely coloured games.

Starting completely afresh with a new character in Nuvema, but encountering the old characters along the way - I particularly like the idea of Bianca working alongside Professor Juniper, not so keen on her being the professor herself - a lot of time would have had to pass.
I also really want the battle frontier to return, although I think that it is probably a given.
A more farfetch'd idea would be to be able to connect to your own Black/White game and somehow download your first Hall of Fame team, meaning if/when you fight Hilbert/Hilda in Black and White 2, you fight your own team from your original games, not at the same level or even same movesets, just the same species.
