So to be clear here, the types are fake but the megas are real?

indeed, more should be revealed soon hopefully.

I assume that all these will be patched into X and Y?

Yeah you would think so, although the only way to get them would be to trade with somebody with ORAS. The Latias and Latios one is already in XY, their just isnt a stone for them.

Reshiram, Zekrom, Dialga, and Palkia are in the game as well?

WOOT

Hoping for Kyruem as well!

UPDATED OP

OMG Im loving the design of the new Megas. Wonder if either will actually be good enough for my competitive team though.

Having all these new mega EVOs without having them being usable in fights would suck.

More updates added to OP

We all know Gamefreak was paying attention to the popularity of Bird Jesus ;)
