There is not enough time left! If the new iPhones feature force touch, then Apple has been internally (and with selective developers) testing it all along, in parallel with the developer program betas and public betas. For those who aren't upgrading their phones, Force Touch is probably not going to be an issue. Phones without the necessary hardware won't be able to access the force touch routines; no matter how hard you jab at your screen it won't trigger a call to any Force Touch API.The Beta is still far too buggy, they could do with stabilising it before adding new features.
