POKEMON GEN 6 ANNOUNCED

[Koh]

I honestly don't get why these mega forms are so stupid, they're going to introduce a whole new dynamic to competitive pokemon, and give some pokemon that were never able to be competitive a chance to be competitive.

That's what plain old evolution is for, though.

As for previous regions, it was postgame content, which is fine. Let us soak in the new region, then have fun going back to an old region to see the changes to it after X number of years. For Gen II/IV remakes, it was 3 years later, so Kanto changed quite a bit. If X/Y allowed to visit Hoenn, that would actually be amazing, since the region was left along with the GBA.
