I don’t know if it’s accurate to say “announced” but this joystick has been listed on Play-Asia’s website for both PS3 and XBox 360 – http://www.play-asia.com/Dead_Alive_5_Stick_for_PS3/paOS-13-49-en-70-5251.html
Release date is late September, currently the 27th.
It’s a reuse of the Noir cabinet that Hori debuted with Hori’s Soul Calibur V joystick…
What shocks me though is the PRICE! I wonder if it’s a Japanese Hori Store/US exclusive OR has Hori raised joystick prices??? The listing price for this joystick (likely NOT to be that popular) is $250!!!
