Update 2: And general attendee tickets are gone, too. Registration was open for just 28 minutes, meaning tickets sold out more than twice as quickly as last year. Congrats to those who managed to score one!
Update: Twenty minutes in, and academic tickets already appear to be sold out.
Original story: Grab your credit card and your Google account and head to google.com/io, because registration for the Google IO 2012 developer conference is now open! Last year's conference sold out in under an hour, so you'll want to hurry to get your ticket, if you're interested in seeing the latest and greatest from Google and its partners this Summer.
Last year we got our first look at the revamped Galaxy Tab 10.1 and Google's "Chromebook" laptops, as well as the first hints about the direction of Ice Cream Sandwich. This year we're expecting more tablet and smartphone goodness, along with more on Google's entertainment services, including Google TV and Google Play.
This year's IO has been extended from two to three days, and runs from June 27-29 at the Moscone Center in San Francisco. Tickets will cost $900 for general attendees, or $300 for academics, double last year's prices. We'll be there, of course, so keep watching our IO landing page for more news as the event approaches.
