ORAS Mega Evolutions discovered via datamining before being announced:
None, the only new discovery is what is agreed by most to be an alternate form of Hoopa, not a Mega Evolution.
0/20
In other words, it would mean that EVERY NEW MEGA IN ORAS WAS ANNOUNCED BEFORE THE RELEASE OF THE DEMO, LET ALONE THE FULL GAME.
Announcing everything over a month before the release of the game is a retarded mistake to make, and that is marketing 101. Furthermore, it was a mistake they knew not to make in the weeks preceding the release of X and Y. I have a hard time believe they would take a step backwards and do this now.
