darn was just about to point this out to you guys.
The fightpad if legitimate is a major indicator of multiple major fighting games coming to switch this year. UMVC3, Tekken 7, and Injustice 2 are all candidates for the launch window, and MVC:I would be a fall release.
Relatively easy process of porting, with slightly inferior graphics but full gameplay, low invest cost, and fightpad compatibility would make the switch the ultimate training option for Fighting games on the go, even if another system was chosen for the finals themselves. This would benefit the developers, Nintendo and the players, while having the potential of increasing the playerbase
