^ it has done gameplay footage of the trainers walking around, May riding a bike on the cycling path near Mauville, shows off Mega Sceptile and Swampert in-battle, but most exciting of all to me is that Diancie's Mega Stone it says at the end of the trailer will be obtained in OR AS, and that distribution details for getting Diancie in X and Y will be coming soon

[Hahex and Oshawott]

i'm convinced that the best thing in this game is going to be steven.
