Sprint maybe moving to LTE and slowly killing off WiMax

Months ago Sprint and there partner of WiMax Clearwire were both considering switching from WiMax to LTE. Both companies saying that the switch would be very easy as they need to just switch out some minor hardware and do a software update. Well looks like Sprint is on track to do that over the next few months. Seeing as Verizon and AT&T are both already committing to LTE with T-mobile not far behind them. So we may all be unified on the same network one of these days in the near future. Question is what will happen to WiMax and the Evo 4G, Epic 4G and Evo 4G shift. hmmmmmm
