From Gamertell:
"Named the You Rock Guitar, this is an honest-to-goodness string guitar (OK, a digital string guitar) that plugs into your computer. For $20 more you can get a GameFlex cartridge that adapts the guitar to be used as a controller for consoles games including Guitar Hero and Rock Band.
The You Rock Guitar will be available in February 2010 for $179.95 but will be on display during CES 2010 at Booth 5627 Gaming Showcase, LVCC, North Hall Las Vegas Hilton East Tower Hospitality Suite H2549."
