IGN reports that Capcom announced that a Devil May Cry 4 demo will be released for Xbox 360 sometime before the game is releasing. The demo that is shown at E3 is completely the same that was shown for the first time in April, so no real new footage of Devil May Cry 4 is expected.
Capcom will be releasing an Xbox 360 demo sometime before the game releases. Capcom is also 'considering' a demo for the Playstation Network, but nothing is certain. A demo for PC is not mentioned. The demo will probably be the same as the E3 demo that is shown in Santa Monica.
More great news about Devil May Cry 4 as Capcom will be showing new levels of Devil May Cry 4 at the coming Game Convention or Tokyo Games Show events. The next demo will also be running on Xbox 360 hardware, in stead of the PS3 hardware where the first demo ran on. A releasedate for the demo or full version of Devil May Cry 4 haven't been given.
