The registration date for I/O has yet not been announced. Last year, tickets went on sale in March, but with the later date for the conference this year, it’s difficult to predict when Google will open up ticket sales. This year, though, Google will be using a lottery system to hand out tickets to interested developers.
Also, quick note for those who want to join in person: this year we’re making some changes to registration, so you won’t need to scramble the second registration opens. We’ll be implementing a new system, where you can submit your interest to attend Google I/O 2014. Successful applicants will then be randomly selected and notified shortly thereafter.
For those who don’t receive a ticket, the keynote and the remainder of the event will be live streamed over the Internet.
