A couple weeks back the British Board of Film Classification gave the title a June 24 release date for Europe. We expect Capcom to officially announce the title shortly.

The retail version will be available on Xbox 360 and PS3 on June 24 and 28 in Europe and North America, respectively. The PC version will hit the streets in July.
