Probably not unless we get a remake in the far, far off future.
Yes when you complete your game
you can get all the pokemon in the Unova region in pokemon black and white, in the other games you all the pokemon in sinnoh, hoenn, kanto and johto. Unova came out in 2010 and shortly after that they thought of a game / 2 involving Unova region pokemon.
Pokémon Black and White.
Sceptile
Pokemon gray might come out in spring 2012, but it is still in the Unova region
Including Genesect:-155 Pokemon in the Unova region.
Yes. IF Ash finishes Unova they might make another game.
Pokemon can not transfer backwards. You can get Pokemon from other games to Unova, but the opposite is impossible.
yeah the is the japanese version releasing on 12 may 2012 trailers are not out
No because , the unova region has different qualities and settings. so you can only catch unova pokemon. but there is a cheat to get celabi to unova.
you can't trade, you have to transfer non-unova Pokemon, and they can never go back to their original game card
dude unova is the region not a city
