Google has announced that registration for Google I/O will open on March 13 at 7a.m. PST. Last year, the event sold out in just 20 minutes, so you'll need to be on top of registration to make sure you reserve your spot at the event. Last year, Google unveiled the Nexus 7 and other products.

This year's I/O will take place May 15 to May 17 in the Moscone Center, located in beautiful San Francisco, California. To register for the event, you'll be required to have a Google+ account and Google Wallet buyer account. Prices remain the same at $900 for general attendees and $300 for academic attendees.

More information can be found on Google's I/O page.
