It looks as though Google (GOOG) is almost ready to start taking registration applications for its 2013 Google I/O conference. The company’s official I/O website on Friday posted a notice that registration for this year’s I/O will start March 13th and 10:00 a.m. EST, or just over two months before the conference is slated to kick off in San Francisco on May 15th. The announcement also urges prospective attendees to set up both Google+ and Google Wallet accounts, although it’s not clear if signing up for both of these services is a requirement for attending.
