I don't think you can really claim "full browser support" with an asterisk that says "assumes latest beta". That's really not helpful when you're trying to figure out if you can actually use something. That said, this is a pretty nice preview of what's coming with CSS3.

(If you are looking for that kind of information, http://www.quirksmode.org/compatibility.html is by far the best resource I've found anywhere online for it, although I don't think it includes all of CSS3.)
