While Google I/O registration won’t open for everyone for another week or so, attendees of last year’s event are now receiving their go-ahead for pre-registration for the biggest Google event of the year. Those individuals registering early are even entitled to a special discounted rate, but space is limited for registration at that price. We’ve received word that some of last year’s attendees have already completed registration for this year.
You won’t be able to register if you did not receive and early invite, so if you didn’t find one in your inbox you will have to wait like everyone else.
