Personally I think its pretty much ready to go. Only items outstanding are phrasing (99% of the templates already are phrased) and documentation.
Couple that with the fact I emailed all users 3 hours ago and there has been a pretty constant buzz on the site since then with people downloading and I have yet to see a bug reported (knock on wood). Thats always a good sign as the most frequent bug reports are directly after a release.
Anyhooo... I say go for it. If you're still cautious then hold off until RC2. At this stage I may even skip that
