Here's my comment:
See, I know that they're posting a tentative 2010 release. But at the earliest, that's still AT LEAST four months away. In my opinion, that's more than long enough for the world to end, much less for the wiz kids at Blizzard to change what they've announced. While I'm really excited about some of the things that they've announced (retooling Azeroth, anyone?), I'm not gonna hold my breath until I can see an end in sight. Like, right around the time they announce the date of the release.
Okay, one more comment. Is it just me, or are Worgen totally slanted toward Huntery-types? Specifically, hunters that do skinning? Good heavens, about three minutes after Cataclysm is released, all the Alliance starting areas will be swarmed with new Worgen Hunters. Provided, of course, that making Hunters use Focus like bloody Rogues, damn their eyes, and that making our shots cost 30 to 60 Focus doesn't completely nerf Hunters into oblivion. It's possible.
