Pokémon Black & White (be warned: spoilers)

GameFreak’s director seems to confirm the notion that Black and White will contain all new Pokemon without bringing back the oldies (until you get the National Dex).

Best news ever.

this mean that the dex will be noticeably larger than previous generations, right?

I mean they have a massive region to fill, so they'll have to add tons of new Pokemon
