Something just occurred to me. I found it a little weird lopunny of all pokemon was getting a mega in ORAS as obviously, it's fourth gen, and it's the only pokemon getting a mega in X and Y so far that is not from 3rd gen (sans Diancie, which I think I heard you get it's mega stone in ORAS or some shit like that? IDC that's stupid)

and, I also realized Buneary and Lopunny were unobtainable in X and Y without transferring from past games. It might just be a coincidence (and it probably is and this theory is probably stupid), but what if it's not? What other unobtainable X and Y pokemon will be getting megas in ORAS?
