Microsoft Windows 8
Microsoft's newest operating system is getting a beta release in February, but the software giant is expected to show off Windows 8 in Las Vegas as well. The tablet-friendly OS has a brand new home screen designed for touchscreen input and will come with a Windows Store for applications. The Windows 8 developer preview was released earlier this year to mixed reviews, so this year's beta build will hopefully give us a better idea of what's really coming with "Ocho."

Can Microsoft replicate the success of Windows 7 so soon after that operating system's release? And will Windows 8 get Microsoft into the tablet market before it's too late? There's a lot riding on this one.
