We aren't seeing a pokemon trainer, period. Sakurai said that each character will have their own moveset, no changing it mid battle (he mentioned pokemon trainer I think, and samus becoming ZSS after final smash).
This is the first time I won't be getting a pokemon game on release, getting smash 3ds then the 100$ Wii U smash bundle. I already played Ruby/Sapphire, so why wait for something I played before? (Not saying its the exact same, but the game is literally a copy of the hoenn region with new pokemon added). [I love ORAS, dont get me wrong]
I, for one, welcome our new roster overlord. The leak is confirmed by now, Nintendo felt the need to comment on it, Nintendo of america themselves removed all videos with the leak, and the huge imgur collection showed Spectator mode and betting. What was pic of the day today? Spectator mode+Betting. Duck hunt dog seems like a really fun character and looks slick!
