I was checking the decent review on these on IGN. Now I'm wondering if I should pick up the 360 version instead of the PS3 and maybe one of these if the D pad will work alot better then the 360 controller. I do however have a DOA fighting sick so I could easily use that just as well I'm sure. They are also available for the PS3.
They look pretty cool.
IGN gave them a 8.7
