Google I/O registrations were supposed to open in just a few hours so developers and people who love free stuff could deluge Mountain View with applications. That's not happening, though. The Google Developers G+ account has posted an update stating the registration window has been pushed back to next week.

Google says the change is being made to ensure the registration process is "even easier." Let's be honest – something probably wasn't ready in time. The new window opens Tuesday April 15th and closes on Friday the 18th. That's a day longer than the previous window that was set to open in a few hours.

This is the first year Google is selecting I/O attendees by lottery rather than on a first come, first served basis. All the applications submitted in the registration window will be in the running for tickets, which will be distributed in (hopefully) a more fair way. If you get selected, you still have to pay $900 for the ticket ($300 for academic folks). Still not a bad deal when you figure in the free stuff Google is probably going to hand out.
