I believe that they will. There have been too many press releases crowing about how soon they could switch to LTE. If you love the woman you're with, you don't brag to anyone who will listen about how you could dump her for another lady whenever you feel like it. As far as Wi-Max being the incorrect path. I do not know if it is true, but nearly every Sprint-phile who defends Sprint for making that choice has insisted that Sprint had to use its spectrum or lose it and Wi-Max was ready and LTE was not at the time. If this IS the case then it would be nice if people would stop whipping Sprint for making the decision it did.
