Pokémon X and Pokémon Y

Agh, to be honest, I think the idea of "Mega evolutions" to be kinda dumb. But I've been pretty accepting of all other Evolution Stone evolutions, so I guess I'm being a little hypocritical, though.

Don't get me wrong, all the evolutions look really badass, and some of the Pokemon getting them are awesome (pineapple yeah upgraded Absol and Lucario and Mawile), but something about it just irks me. Also, was the new Mewtwo not confirmed to just be an alternate form? So now it's a "mega evolution"? I'm guessing at this point that there isn't going to be a second alternate form, like has been speculated, as that means the other form would be another new Evolution Stone.

The thing that annoys me the most with this: taking up 1 of the new Pokemon slots for a starter "mega evolution". That's just dumb. It's going to annoy the hell out of me if Blaziken ends up being the only one with a "mega evolution" and no other starters get one, too.

Also, Ampharos' mega evolution look:
"Alright, so these other Pokemon got really badass designs for their new evolutions--new color schemes, extra spikes and protrusions, the works... now for the last one and we're done for the day. What should we do for Ampharos' evolution?"
"...We give him long, flowing Fabio hair?"
"Genius!"

EDIT: Okay, apparently it isn't through a new stone, my bad. Got the wrong info. Disregard some of this post.
