Resident Evil 5: Alternative Edition , announced at TGS 09, will be available in North America, Europe and Australia in the form of DLC on Xbox LIVE and PSN, so you might want to hold on to your RE5 disc. Japanese gamers will be getting the new content in physical form but a quick survey asked the Capcom community in Europe, North America and Australia to state their preference, close to 1500 people voted for DLC and close to 900 voted for a new physical product which persuaded Capcom to go with the DLC release.
A blog post on Capcom Unity said, "You will not be asked to purchase a new copy of the game just to get at the new stuff, just make sure to hold on to your RE5 disc and you’ll be ready to roll in Spring 2010 when we make available new Resident Evil adventures (and some other things we haven’t told you about yet) for you."
The PS3 version of the DLC content will feature full Sony motion controller support currently under development. Below is the announcement trailer shown at TGS 09 -
