No. This is normally when they ramp up production for a fall release so not going to see it any earlier. Apple, even starting in july still won't have enough for launch so no way they bump up the release, not to mention with IOS8 on only beta 2 it still has lots of work before it is ready for prime time and a GM release
Probably because the 5S could have been released by July if Apple wanted to. There wasn't much design difference from the previous gen. With Touch ID and the new camera stuff, Apple probably decided on a final product sooner than they did this year.
