We'll see Apple utilizing their "sold separately" nature they are becoming known for.
I find it unlikely there will be an adapter in the box.
You can currently goto the Apple Store buy a new MacBook and iPhone for 2000+ dollars and not be able to plug them together without buying an adapter too.
AppleTV 4 requires you to supply your own USB power albeit that's not typically that difficult however to restore one via iTunes you'll need to buy a USB C cable.
And now the iPhone will require an adapter to use current headphones and other accessories.
Business as usual.
