As excited as I am about gen 6 already being revealed, it does tip me off a bit to see it start too soon though.
But there's no doubt that gen 5 is the best generation of pokemon so far. It does have the best pokedex of all the generations. As for the games themselves, B/W were still on a tie with gen 3 for the first place, but B/W2 completely blew me away with their awesomeness. So much to do, so many memorable characters, so much.....MORE than everyone expected. Even though the new Kyurem forms were ****.
