Systems games are being played on? (to know what pads/sticks to have)

I’m interested in playing this year but I couldn’t find a listing of what games were being played on what systems in the case of the ones that are multiplatform. Sorry for the newb question just couldn’t find the answer. This is a concern to me as I don’t have next gen sticks/controllers for ps4/x1.

What platforms will Guilty Gear Xrd and Mortal Kombat X in particular were curious to me.

Also if you can use the Wii U Pro controller for Smash 4.

Thanks for any help to my questions!

MKX will be played on PS4.

GGXrd will be played on PS3

Wireless sticks/controllers are banned as well.

The Pro controller is legal, but it’s better to bring a corded controller for the game just in case. The Wii U it self is banned from being used as a controller.

Due to USF4 being on the PS4 this year, the event is going to provide sticks for the players. It maybe possible to use one in GGXrd, but it’s very unclear if that is a option at this time.

If you have old controllers, like a Dreamcast controller, you should bring it to play in side tournaments.

what about dual modded sticks
