Update: Apple's WWDC 2016 page is now live. The event will take place both in Moscone West and in the Bill Graham Civic Auditorium, the same event space where the iPhone 6S, iPad Pro, and Apple TV event happened last September. Apple's schedule says the opening-day keynote will be moved to the larger space, while the actual developer sessions will stay at Moscone. It also confirms that the company will talk about all four of its major platforms—OS X, iOS, watchOS, and tvOS—in the opening-day keynote.

Developers can register here for their chance to attend the show, which costs $1,599. Registration ends on Friday, April 22, and developers will know whether they were selected by Monday, April 25.

Original story: Apple hasn't officially announced the dates for this year's Worldwide Developers Conference yet, but Siri will blab about it if you ask. Apple's personal assistant says that WWDC will run from June 13 to June 17 in San Francisco. The location hasn't been confirmed, but the conference has historically been held at the Moscone West event space downtown.

The official WWDC site hasn't been updated with the new information and there's no way to register to buy tickets yet, but if Siri is telling people the date, we'll probably get more information soon.

Apple has historically used its opening-day WWDC keynote to show off new OS X and iOS versions, and watchOS was added to the rotation last year. We may see a next-generation version of tvOS, too, now that the Apple TV is a full-fledged platform unto itself. Rumors haven't told us much of what to expect, but OS X may end up getting Siri and a "MacOS" branding change to bring it in line with Apple's other platforms.

Apple has also been known to use WWDC to announce and release new Mac hardware, though it doesn't always happen. The majority of the Mac lineup—including all MacBooks, the Mac Mini, and the Mac Pro—is due for a refresh with new Intel CPUs and other improvements.

We've contacted Apple for more information, and we'll update this post with more WWDC information as we have it.
