Well Sayzo your wish maybe coming true looking at this chart:
Woah are They serious !? So all the geneation1-5 starters are getting mega-evolution and they giving Tyranitar, Salamance, Dragonite and Gyarados mega-evo's too!? Thier stats are going to be crazy. I am also curious about how Zoroak look in mega-form.
Your right its powerful enough already. Just to think Cynthia owns Garchomp, Lucario, and Milotic she lets them hold mega-stones and she shows up in Kelos and you have to battle her. Now that will be a hard battle
[then agian I don't mind her being more challanging in every game she appears. ]
