Keiji Inafune, the head of Research & Development and Online Business at Capcom has explained why the company made the move to make DMC 4 multi-platform. One of the key reasons is that Capcom has created a development engine that allows for easy exportation to the PS3 and Xbox 360. He explains that the Xbox 360 exclusive Dead Rising and Lost Planet helped to complete the engine which is now complete.

Until now it's been hard for us to develop multi-platform games, but recently we have developed this development engine that allows us to develop a game in the engine and then put it on to PS3 and 360.

Developing Dead Rising and Lost Planet helped flush out everything in the development tool system — which is now pretty much complete, aside from the usual upgrades — so we decided to use that engine, make it for the 360 and the PS3 with Devil May Cry 4.

So, now we can get the game out into the hands of more gamers — because 360 has such a huge installed base already, especially in the US, and as game makers we want as many people to have the chance to play our games as possible.
