Today is the day, Apple fans are perhaps a little too excited but that's par for the course. We've had plenty of "pre-announcements" and speculation that these have come over the last week because they're running short of time in the Keynote. There's even been an apparent supply chain leak on Reddit (and a handy summary if you don't feel like wading through all those comments).
There are a few WWDC games you can play along with during the keynote (useful if it's 3am your time and you're tired!), so I made a short roundup:
Upgrade #143: Myke or Jason? Who gets more points? There's a PDF scorecard in the comments, and you can listen to their episode afterwards discussing the event and dishing out scores (they have an independent judge incase they can't agree!).
WWDC 2017 Keynote Bingo: From /u/TheMechanoids on Reddit. I appreciate the fact that "one more thing..." is right in the middle - and I hope we get a full house!
Connected #144: Federico, Stephen and Myke decided not to score but to decide who would be happier, Federico suggested the Happy-o-meter, and I threw one together, there was a positive reaction on Twitter so here it is in PDF for you if you prefer that to an image.
Have fun, and remember - even if you don't get what you thought you wanted you might well get something much better.
Personally I've even thrown a WWDC 2017 wallpaper on my watch ;) (Wallpaper available from macerkopf.de).
Oh, and if you're planning on installing the developer betas don't forget to do an encrypted backup first.
