According to PlayAsia, Hori will be bringing out a Dead or Alive 5 arcade stick in time for the Japanese release. This is of course a Japan only release, currently. The arcade stick will be available for Xbox 360 and PlayStation 3, and is based on the Soul Calibur V Hori Arcade Stick with what looks like an art replacement to that of Kasumi, Ayane, and the "I'm a Fighter" slogan.
The arcade stick is currently set for pre-order on Play-Asia at the current asking price of $249.90 + S&H.
Update: Amazon Japan has posted the arcade sticks with higher quality resolution for both the Xbox 360 and PlayStation 3 versions at ￥14,801 (~$185 USD) making it seem more plausible that Play-asia has buffed its asking price.
Update 2: Amazon USA has posted the Xbox 360 and PlayStation 3 arcade sticks for $149.99.
