I have seen several of the mockups and some validated third-party case options. Excuse the pun but it will be a welcome sight with the larger screen and hopefully easier to type. The not so talked about real benefit will be iOS 8 which will include a greatly enhanced Siri vocabulary. The new processor is needed to better drive Siri's more advanced A.I. interface.
As always, this is based on the various sources available on the net but I tend to believe some of it. Frankly, I need a new PC before upgrading my phone and I'm still debating between Windows and a new Mac.
