A Charizard Z would be amazing just to complete Charizard X & Y and A Mega Lugia aswell, but i would Rather that on soul silver 3ds... Would be great if Mega Zygarde, Y'velta, and Xerneas are in Z. i just think the mega evolution was a big step and i susupport it alot !! It would make sense if there's more megas especially that kalos is back on the picture. Like a mega Gregninja or Goodra. Battles would be way more competitive because of what oras can offer like a Mega Sceptile against a Mega Gregninja that would be good fair match. Besides the game would be very different and unique on its on way.
