Microsoft has repeatedly stated that
Xbox 360 is only half of its useful life, making us understand that the console will remain on the market at least until 2015: this does not mean that in the meantime not to leave a new console to accompany the current and is exactly what Capcom seems to suggest. The managing director of Japanese publisher, David Reeves, has explained the site GamesIndustry that the next wave of consoles - the Xbox 3 and PS4 - comes in 2-3 years, so around 2012-2013.
Reeves explained that certain information holds the substance, but it is a realistic estimate: we have to wait and see if it really well.
