I'm the opposite. Currently, Mega Pokemon are over doing themselves. I would have been happier if they were real evolutions for some of the ones revealed. Considering they are only available in battle kills them for me. I would have loved if they stay Mega form as long as they held the item so I can have them in boxes as a Mega. But at the same time, since they aren't considered new Pokemon, they don't add to the Kalos Dex nor National.
Also, when I said make newer Pokemon, I meant make some evolutions and maybe some stand alone. Like say a Hawlucha evolution, or a third evolution for Spritzee and Swirlix. Maybe 30 newer ones for the new games. Not 100+. I mean, if the "70" Kalos Pokemon is true, then 30+ more would be cool to give the native Kalos Pokemon 100. Like Johto had 100 and Sinnoh had 107.
Just my opinion.
