>>28322349Folks think Megas are Gen 6's "special feature" that won't carry on to future games, since each Gen seems to have one of those.
Amie and fashion/customization have been confirmed as returning, so the list of possible "Gen exclusive" features is dwindling.
Howeverrrr given just how heavily marketed Megas have been, and continue to be, I personally think they're sticking around.
Until rollerskates are confirmed in Gen 7, anyways.
