Google’s I/O developer conference will return this year on May 28 and May 29 in San Francisco. Google senior vice president Sundar Pichai announced the dates on Google+ and Twitter, pointing to the official Google I/O 2015 website.

The website says registration begins at 9 a.m. Pacific on March 17 and closes at 5 p.m. Pacific on March 19. Like last year, Google will hand out invitations randomly after this period ends; the company has handled demand issues in different ways in previous years, but apparently, it liked the system it used in 2014. It also hasn’t announced pricing, but last year’s event went for $900 (general admission) and $300 (academic admission).

In addition to the actual conference in San Francisco (the official schedule has been posted, but individual events are not yet available), the company plans to stream the event online via I/O Live. Google will also hold “I/O Extended” events in other cities. They are described as follows:

I/O Extended events may include live streamed sessions, local developer demos, hackathons and more. These events are brought to you by our Google Developer Groups, Student Ambassadors, and local developers.

In fact, you can apply to host your own I/O Extended event. Follow the organizer guide and then submit your event.

Google I/O 2014 was June 25 and June 26. Google used the conference to unveil Android L (which later become Android 5.0 Lollipop), its Material Design mantra, Google Fit, Android One, Android TV, and other various improvements for its products and services.

It’s a tad early to say what will be coming this year, but bet on a new Android version is likely. Chrome and the larger family (like the Chromecast) will undoubtedly also play a major role.

Three months from now, we’ll be on the ground in San Francisco to cover Google’s biggest event of the year.
