GameFreak seems to prefer doing their own thing for Pokemon games, so I wouldn't expect to see Pokemon X and Y in any of the Nintendo Directs or small presentations. At most I would expect a mention of them as part of the 3DS lineup in the Fall.
Pokémon X and Y were announced in a Nintendo Direct segment.
