^What they said^ Heck, I'm not even adding it to my local ubuntu mirror for a few weeks (gonna be a LOT of bugfixing in the next month; what with the massive UI changes, etc) - hold off for a few weeks at least. If you REALLY want to see how it'd run, try cloning your install into a VM and then upgrade that. That will tell you at least software-wise if it'll work - hardware issues beyond that.
