"Of the apps we have tested with Wine, about 20% work well, and about another 20% work but have some glitches."
Just my opinion, but that's a terrible idea to put in the 1.0 announcement. The impression I get after reading this is (1) wine is full of glitches, and (2) it's being released with 80% of the apps not working well.
If you're trying to appeal to new users and/or sponsors you should put more focus on the positives. I don't see Fedora saying "Release features include X, Y and Z, but X has a bunch of bugs" (X might be full of bugs, but you don't point this out in your release announcement ).
