This follows on the heels of MWC being canceled last month — a huge conference with 100,000 attendees — and Facebook announcing a few days ago that its F8 developer conference, scheduled for May, has been canceled.
So: What does this mean for WWDC? I’d put the odds at 50-50 at this point. Apple’s recent announcement dates for WWDC range from mid-February (2017) to mid-April (2016), with the last two years coming in mid-March. So they still have time to decide. If they don’t hold WWDC this year, my guess is they’ll still prepare all the sessions and simply deliver them via the web and the Developer (née WWDC) app, perhaps with a media-only keynote at Steve Jobs Theater.
