While we got Fighting Vipers and Virtua Fighter 2, Cyber Troopers Virtual-On and Virtua Striker are Japan only. The Virtual-On team says Sega has no plans to release the two upcoming arcade games outside of Japan. The decision is odd since Sega brought Virtual-On: Oratorio Tangram over and the Xbox 360 Virtual-On games are region free.
You should be able to download both games with a handy Japanese PlayStation Network and a 800 yen ($8.80) of PlayStation Network credit or 400 Japan-region Microsoft points. Cyber Troopers Virtual-On and Virtua Striker will be released on February 13.
