On Tuesday, Google and Intel will announce news involving Google Chromebooks, and there's lots of speculation as to what the news will be.

Some say the two are going to announce a new Google Chromebook tablet, though Google already has a tablet operating system with Android.

Others think that Google might be announcing an update to its high-end Chromebook Pixel, which runs on an Intel chip.

Or they may be announcing a new generation of Chromebooks based on Intel's upcoming Broadwell chip, a faster, lower-power chip that should be powering new devices later this year.
