Well, some innovation at least: at E3 2002, Sony announced the EyeToy, a widget that allows players to use a USB web cam as an input device for the PlayStation 2. It was presented to the public at this year's CeBIT, currently under way in Hannover, Germany. There are about 15 to 20 EyeToy-games in development, and the device will be sold in Germany in July 2003.

Update: Augh! Sony showed this at GDC and I missed it! :( Bah.
