Will they or won't they? Rumors are swirling about whether Microsoft will introduce its next-generation Xbox 2 video game console at CES this week or wait until the E3 show this spring. If Microsoft does use CES as the springboard for Xbox 2, as it did 3 years ago for the first Xbox, that announcement will come Wednesday night at Bill Gates' keynote address. Either way, details about Xbox 2 are starting to come to light. According to sources, it will play DVD movies out of the box and feature a flash-based hard disk. Still up in the air is whether it will play first-generation Xbox titles. Xbox 2 will launch in late 2005 or 2006
