HMV have now got the wireless fightpads back in stock. PS3 only, recommended if you're not serious enough about these kinda games to but a fightstick, but want to be able to pull of some sweet combos. "Assorted" (whatever that means) sagat and guile avaliabe at this time, the others are pre-orders and are going for more than double the price. I personally have a ken one coming to me for £12.99 from a deal posted aaages ago.
Get some practice in before Super Street Fighter IV comes out = )
