So I guess this means no new evolutions either? Darn, I've been hoping for a Mawile Evolution.

There is a Luvdisc evolution already.
You might just get a Mawile evolution too if you're lucky. But considering what Mawile is based on, I would say that you shouldn't count on it.

[...]
Mind you, it may be something like, "Only evolves into ____ from Mawile while in the region of Issu" or something along the line.

Yep. I agree to that. We will, without a doubt, get new forms of evolution triggers.
New stones, areas etc etc.

And probably another couple Eevee Forms O_O.

 The graphics look awseome, and the game looks interesting. I hope there's absol evolutions. (or a pre-evolution and one evolution) I can't wait for this game, the screenshots make me think about how the graphics and gameplay changes will affect the game.
