re: Mega Mightyena, I know a lot of people want one, but I can't see it happening. Just because a Pokemon's weak doesn't mean it has a higher chance of receiving a Mega; plenty of "powerful" Pokemon (including legendaries and pseudo-legends) have received them. Plus, it seems like Megas go to more uncommon/rare Pokemon--ones that aren't found in too many places, even in Trainer battles. Poochyena and Mightyena are pretty common, and are one of the most used Pokemon on Team Magma and Team Aqua XD I'm not saying that common Pokemon don't have a chance of receiving Megas, just that it seems less likely. It's a similar deal with Linoone.
Of course, there's always the possibility of Mightyena and Linoone receiving a boost in at least one of they stats, but I feel that such would've been done in XY, so chances of it happening are rather slim.
