Well out of the said Pokemon in the image:
This is the list of Pokemon that will Mega Evolve.
So far we have the following covered:
-Venusaur
-Charizard
-Blastoise
-Kanghaskhan
-Mewtwo X and Y
-Ampharos
-Blaziken
-Mawhile
-Absol
-Garachomp
-Lucario
Tell me if I missed any. Wayne is not gonna be happy for Gardevoir/Galade and Serperior.
Also I hate the fact that everyone likes Charizard and Blastoise. Weren't they good enough before the MEGA MANIA arrived? No one likes Venusaur because of how it LOOKS.
I don't care how a Pokemon looks like. I like it for the power. Charizard will fall down and cry at the mere sight of stealth rock! Fire is weak to Rock. Flying is weak to Rock. And besides Charizard, there are so many other options! Volcarona evolves only once and it still manages to live better than my Charizard. It can't even stand one of the most common moves in game! Stealth Rocks I mean god just why is this no god please why Nintendo just shut up.....
