It appears that the as of now PS3 exclusive Devil May Cry 4 is on it's way to a few other consoles.

A press release found on Capcom of Japan's press site dated March 20th, 2007 announces the news. http://ir.capcom.co.jp/news/html/070320.html

UPDATE - Doh! Someone in the neogaf.com forums beat us to it...and with an English link! http://ir.capcom.co.jp/english/news/html/e070320.html

A rough translation of the page states that a decision has been made to develop Devil May Cry 4 for the Xbox 360 and PC. No release date or other info was given.

Stay tuned soon as hopefully Capcom will announce details on a US release. I am just as excited for a PC release as I am for the 360. Just one more reason for me not needing a PS3.
