they thought enough to create the title "Pokemon Direct", so my guess is that there will be more of those down the road. the entire non-trailer segment of the pokemon direct seemed like they were getting at something else. i'm sure there's a lot left unmentioned still.
I think at the end of he direct Iwata meant they'll release some old Pokémon games for 3DS VC. (and can trade with X/Y, MEGATONS)
