Oh man, I hope I can find a ps3 one. Already have a 360 one but recently switched my online gaming from 360 to ps3. I need to figure something out before Marvel vs Capcom 3 comes out!
I don't think so. I did a little looking around a couple months ago, hoping to use my 360 stick with my new ps3. Not much luck, I think they're totally different. I'd love to be proven wrong though!
A modding process can be done to make your stick 360/PS3 compatible, there are articles/videos with directions out there, probably on shoryuken.com. It requires a soddering iron and some additional parts, not sure if it's worth the trouble for just an SE.
Round 2 TEs are going for $99 on the gameshark store. If you factor in the fact you'll be buying new buttons for an SE, it's really only like $35 more for the TE in comparison. I'm still using my SE after a year and it's well worth the money, but I kind of wished I got a fancier one now that i love playing stick.
just something to keep in mind.
