Sony held the PlayStation 3 close to its vest at CES, with only a few game trailers playing in a loop and a system mockup under glass. The only real details available are that Unreal Tournament 2007 and Metal Gear Solid 4 will be PlayStation 3 games, the system will play Blu-ray discs, and Sony is still sticking to the boomerang design. Rumors have circulated around the CES floor from certain manufacturers in the Blu-ray camp that the PS3 will cost as much as $800 and will be released in early 2007. Of course, these rumors were being spread by companies that are producing competing Blu-ray devices. Hopefully, Sony will reveal more details about its next-gen console at E3 in May.
