Google will hold its tenth-anniversary I/O developer conference May 18-20 in Mountain View, CA, CEO Sundar Pichai said in a Tweet on Tuesday. It’ll take place at the Shoreline Amphitheater, a massive outdoor concert arena (yes, a developer conference held outdoors), and the most likely big reveal would be a peek at Android’s newest version, Android N, rumored to be named after an Indian dessert.

Google could also share more details about its Project Tango 3D-enabled smartphone, settle the question of whether it’s merging the  Chrome OS with Android, or show off some of its self-driving cars.

Developers who can’t attend in person can tune in via the I/O Live stream or check out an I/O Extended event in their area, said Pichai.

Meanwhile, registration opens Jan. 19 for Microsoft’s Build 2016 conference, which runs March 30 to April 1 in San Francisco’s Moscone Center. Tickets are $2,195 and include access to technical sessions aimed at helping developers build better Microsoft apps—as well as, if tradition holds, a free device or two.

Microsoft is so far mum on details of the event, but exec Steve Guggenheimer said in a blog post that the conference will reflect “the shift to a cloud-first, mobile-first world.”
