Will x86 Surface Pro run Ubuntu on Day 1?

If the Surface Pro is essentially a very tiny all-in-one PC... couldn't it run an Ubuntu install right out of the box?

If so, that means Ubuntu indirectly released their first tablet yesterday as well. I use Ubuntu as an example because you could make the argument that we already have Linux-based tablets. Then I'm wondering if Chrome OS could find it's way on there as well.

... or if I can transfer an old WinXP license over and dual-boot... hmmm....
