OMEGA RUBY and ALPHA SAPPHIRE corocoro leak

Okay so, a couple of things stood out to me about the leak:

. Team Aqua, both the leaders and grunts seem to have been replaced by all black people?

. Mega Diancie even though Diancie has yet to be released.

. Mega Sceptile, Mega Swampert, Atom (Mega) Groudon, Atom (Mega) Kyogre, ok cool.

.  Aaaand we have pictures of the climax of the game? Why?

. All before E3?

. I have to admit from the 1.overworld pictures shown, and the 2.battle footage; 1. the graphics seem to have been taken a notch down from X and Y, it almost looks more cartoon-like, 2. and the battle footage seems to be a carbon copy of X and Y.

.  I am not too thrilled with the character designs.

.  Steven Stone returns with a Mega Charizard X, you know because a predominantly ground type trainer needs a fire dragon type.

. Again, all before E3?

. They Might as well release the whole game at E3
