Reports have long suggested that Apple has been working on a trio of new iPhones for 2018, and now we know when we'll actually get to see them. The company just sent out invites for an event on September 12 at its massive spaceship of a campus in Cupertino -- one year to the day from last year's event, no less -- and one thing is already clear. It's going to be a very busy morning.

Get ready, nerds!
