It will be interesting to see if consumer electronic devices (DVD/BR players, refrigerators, thermostats, gameboy/PSP, cameras, etc) end up with LTE since it is controlled by 3GPP (the telcom industry).
CE device makers are tied into IEEE, which controls WiFi and WiMAX. If WiMAX fails, LTE may stunt the possibilities of all kinds of devices with 4G as 3GPP is not friendly with IEEE. IEEE is a more open, more consumer friendly than 3GPP. If WiFi (or ethernet) were under control of 3GGP, it would never have become this ubiquitous.
I suspect that Sprint will eventually convert the CDMA network to LTE, still tied into the telcom industry. They will continue to have a foot in WiMAX but it will be an IEEE/cable industry thing and does have it's place. It's a growth opportunity for Sprint that the other carriers are not taking.
I hope to so both WiMAX and LTE in the long term. As consumers, we should want WiMAX to survive. We'd likely see far more consumer electronic devices on 4G.
