This is not directly related to the Fightstick, but I went to my local Fry's in Woodland Hills, CA yesterday and they had some PS3 Fightpads in stock. If there are any cags in the area you should go ahead and pick one up.
I wouldn't trust DD with my pre-order. I ordered SFIV CE for PS3 over a month and a half before it came out and it never came out of backorder. I got lucky and found one at Gamestop.
Got my copy on Monday. I also received my code from Amazon last night for the Killzone Home costumes! They are pretty sweet.....Too bad Home sucks right now......
