Just got done watching a segment of Jjimmy Fallon tonight and Reggie, Bill, and Miyamoto were on the site. (Miyamoto played the Mario theme with the live band!!!) There were some amazing highlights but the biggest was the fact that the Switch was hidden under a coin block the entire time before Reggie pulls it out and proceeds to play Breath of the Wild right there. It looks amazing, no frame drops from what I saw. I have no way to post any video footage, somebody will probably post better info in the morning (cycycychris provided the video)but damn, I wasn't expecting it to fucking be there.
More Mario Characters Playable as well!
