Will Nintendo announce a new Pokémon game at E3?

[Metrium]

We had two pokémon games in the two past year (or 4games depending on the way you look at it). X/Y in fall 2013 and AS/OR in fall 2014. So it is not too to think that nintendo is aiming to make the franchise yearly and that we will see yet a again a new pokémon game this fall. 

Personnaly, I think X²/Y² is the most likely since Zygarde is to lame, useless and boring to highlight a Pokémon Z game.
