Kay, so if B2W2 are sequels with a brand-new adventure...

aaaaaaaand they are in the same generation as BW...

I think no one really expected it from anywhere, no? You mean, brand-new games, sequels, direct ones, same generation and all the stuff that it implies?

This is sounding a bit strange. I just hope that everyone knows what's going on in here... It's quite the unexpected thing, to be honest, but from the looks of it judging from the CoroCoro leaks, I guess these are no third versions.

(BW = never had a "third version". Hahahaha!)

Nintendo filed a patent for Pokemon Grey like 4 years ago, so.....

I'm assuming both games have the same story, but different from the original B&W. You can consider it a 3rd game, but it's like a 2 for 1 sale. ;D

Nintendo files patents for names all the time. Doesn't really mean they're gonna use 'em.
