I agree with you Eric. Once Clearwire transitions it's entire footprint to LTE, there won't be any reason for them to keep WiMax going. When the time comes to turn it off, they will offer their existing customers slightly lower prices to get newer data cards to switch to for LTE and then those who refuse to switch, they will just lose their service. WiMax is just going to be too costly to maintain once LTE goes live, and then Clearwire can use that extra capacity to pump out better data speeds for LTE.
