Google I/O 2017 is set to take place in mid-May this year, and like with the past few years, attendees actually have to register that they are interested in attending this year, and Google will randomly pick people to attend the developers conference. The reason why they went this route is because selling tickets normally goes very quickly. Google I/O tickets would typically sell out in seconds, literally. Making it unfair for many people that want to attend, but just don't get the time. So now everyone gets to register that they are interested and everyone has an equal chance of being able to attend.
With the period of registering interest having just ended yesterday, Google is now notifying general and academic attendees that they have been selected to attend this year's installment of Google I/O, which will be at the Shoreline Amphitheater, the same location as it was last year (also the same place as their very first Google I/O over a decade ago). Google did raise the price of admission this year, with general attendees costing $1150, and academic attendees paying $375. That's a $250 and $75 increase respectively. But that is just about the same amount that Apple charges for their developer conference - WWDC - in San Francisco every year, so it's not a huge increase really.
Rumors haven't yet started swirling for this year's Google I/O, but many are expecting the search engine to give an update on the Google Assistant, which debuted at last year's Google I/O. As well as show off a few more features of Android O - if they keep the same schedule for Android O as they did Android N, there should be a developer preview on the way shortly. Among their other products. The keynote is usually full of mostly software changes or new versions that will be available publicly later in the year. Like Allo, Duo, Google Assistant and Android 7.0 Nougat from last year. Google I/O is always a pretty popular event, and many call it an Android fans Christmas, seeing as Google unveils plenty of new goodies, both for enthusiasts and developers. If you were selected to attend this year, your payment method will be charged in the next few days, so you'll want to be sure that cash is in that account.
