Correction Network Vision cell sites will never have WiMAX on them. To start, they'll have PCS 1x/EvDO/LTE turned on. Plus, in some caes, 1x at 800MHz. Later, they'll turn on LTE at 800MHz, once Nextel/iDEN is gone (RIP tape-measure-sized phones). Around this time, assuming they're still around, Clearwire's 2.5GHz TD-LTE will be integrated into that infrastructure on an as-needed capacity-focused basis. No WiMAX though.
Side note: until Sprint has LTE deployed over a large area (at least larger than AT&T), they'll have to keep unlimited data for smartphones as a differentiator to keep people on their service. Once they have a network that's as fast, if not faster, than AT&T/Verizon, then they might start looking for ways to increase revenue (i.e. limited plans). However my bet is that even then they'll have better pricing per gigabyte than Verizon or AT&T (I'd expect $30 to buy 5GB of data at that point).
