Fulfilling a promise made in June, Microsoft is trotting out a new firmware update Tuesday that lets you access Facebook, Twitter and Last.fm from your TV.

GamePro reports that Sony will be beaten but not outdone, and leaked images of its own PS3 also running Facebook, projecting a similar update on the way someday. It took the PS3 a year longer than the 360 to land Netflix streaming, so don’t hold your breath.

The question remains as to how useful Facebook access will be, but like a Swiss Army knife, it’s better to have it and not need it than need it and not have it, I guess.

The way I see it, Facebook is for sapping away tedious work hours, not valuable “Modern Warfare 2” moments. What do you think?
