Microsoft is throwing a House Party on Xbox LIVE in February and perhaps they are bringing several new games to the two Xbox 360 and Windows Phone 7 including the PC classic Torchlight for an HD remake of Beyond Good and Evil together with Hard Corps Uprising.
The announcement of the House Party promotion came following your Microsoft CES keynote with intends to kick rid of it on February 16. Hard Corps Rising would be the first here game but no schedule was presented as to if the rest are going to be released. Presumably it will likely be one or two games per week over a month-long period and include some other almost incentive to acquire all of the games like previous promotions.
These would be the games as outlined by a Microsoft pr release.
