I'm also hoping for a couple new Eevees....Steel-type would be awesome, and maybe Dragon.
I'm curious if any one will get new evos...I'd like to see a Sawk/Throh pre-evolution. Might not be popular, but Skarmory and Aerodactyl would make good evos. (I'd love to see a Quetzalcoatlus-style Aerodactyl evo). In general, I hope they have some original stuff...I know some are going to complain about the frog and fox starters.
New type combos would be cool too.
