What were your initial thoughts when you saw the scans and information for the new games? Did you think anything specific about what you saw or just some general things that you picked up?
For me, the very initial thought when I read the information was simple: These games appear to be what the original Black and White games should have been in the first place. Not that the originals were bad, I loved them, its just they seemed incomplete in some way. B2W2 seems to have addressed some of these issues.
My second thought is something that I'm betting on RIGHT NOW, and something which I hope is true. Looking at the character designs, they appear very similar to the player character choices from BW. So, I believe whichever trainer you pick, the OPPOSITE trainer was the one that "Canonically" captured Reshiram/Zekrom, stopped N and Team Plasma and defeated the Elite Four. Whether or not they'll still be the champion, will be an end-game boss like Red or we'll meet them during the story is another thing entirely.
So, what did you think looking at the small bits of information we have so far?
