MKX and PS3 Sticks / Pads at Evo

So I just saw this on the front page:

As I’m signed up to play Mortal Kombat X at Evo this year, I had some concerns, seeing as I only have a wired Madcatz fightpad for PS3. If a PS4 dualshock is still needed to use it, I can see how this would be a logistical problem. Will PS3 fightpads and sticks still be allowed at Evo, or will I need to get my hands on a wired PS4 controller after all?
