Well there you go. I'd like to say that I called it (although I did say that voice chat would find a place in a lot of PUGgers' hearts), but I was surprised to see that 70% of you readers expect to use Blizzard's new voice chat feature coming in 2.2. Personally, I'd rather stick to Teamspeak (and I'm guessing my guild will do just that). And I know, from the comments yesterday, that there are lots of people out there who just don't want to get involved in voice chat, whether there's an ingame system or not.
But clearly Blizzard was right to put the time in-- there is a good majority of players ready to plug a mic in and start speaking to each other. Very interesting.
Update: You're right, commenters. Title updated from "players" to "WoW Insider readers," since that's who we actually polled. I only got a B in Stats class in college.
