Alright my theories:
-In the final battle of BW, Ghetsis will utilize Kyurem's original form.
-Zekrom will be passed from N to White.
-In the big showdown between the Unova gym leaders and the Plasma sages, the Kami trio will be utilized and they may or may not show their Incarnate forms (if not, they will by Black and White 2).
-Mewtwo will show up in Unova where it will battle Genesect (which would be pretty cool considering how both of them are mutations created by a villainous team) and Mewtwo will get to show off Psystrike.
-Black and White will change into Nate and Rosa's clothes for the B2W2 chapter.
