>>36272079lol no, there's a reason they haven't been showing much of the game, it's because there's nothing much to show, it's the same pokemon, same region, same characters, but less content.
And from a marketing stand point, there's 3 months left till release, revealing Mega's now is clearly showing they don't have much to show and are stretching out the info and are now acting as if mega's are new and the fact that no new mega pokemon was announced to coincide with the reveal kinda makes it seem like there aren't any new ones.
Also, GF count Mega's as 'new pokemon' and they have already said there's only 1 new pokemon in the game, so....
