Valve Software has pledged its support to the Xbox 360, suggesting that there will be a new game for the console announced soon.
Valve has previously released Half-Life 2 for the Xbox. Despite looking fantastically good given the hardware, and having all of the awesome HL2 gameplay, it sold pretty rubbishly. Perhaps Half-Life isn't much of a franchise outside of the PC space?
However, Gabe Newell has confirmed that there will be a new Valve title for the 360, and that we'll hear about it soon - we'd speculate that there will be something happening at E3 in just a couple of months time. Newell also said that the game would be using a modified version of the Source engine, although we're not sure exactly how it will be modified.
Interestingly, both Microsoft and Valve subscribe to the theory that digital distribution of gaming content is the future, with Microsoft offering its Xbox Live service and Valve running the much-maligned Steam.
