Are Diamond & Pearl remakes going to happen? If they are, do you think they will have Sinnoh forms? ORAS had some megas, and that was gen 6's gimmick. Regional variants are gen 7's, so I don't see why not. They would have to be Sinnoh forms of gen 5 mons though, as gen 6 came out too recently and gen 5 mons weren't in the original gen 4 games.
