It certainly seems as though the X360 should be able to handle rendering scenes from different viewpoints, and then alternating the output in a 120 Hz signal, if that's how the 3D stuff works. MS probably just didn't have the TV hardware, or a high end > 60 FPS, 1080p game to show off at CES.
I'm sure Sony knew in advance, and had the TV know-how to either make it work with existing 120 Hz TVs, or had some special TV prototypes, perhaps only with different firmware, at the show. The fact that MS didn't have 3D apps showing at the show may not have anything to do with the 360's capabilities, given certain assumptions on how the tech works.
