Here's the thing: Palm announced the Pre3 before carriers signed on to carry it. That's why they haven't announced anything more than the bare basics of the phone. We know either Sprint or Verizon will be getting the Pre3.

Also, HP/Palm can't yet announce if it has WiMAX or LTE, because in order to confirm that, they would need to have confirmation from the carriers that they would carry it, which we know they don't have yet.
Also, I would expect that Verizon will get the Pre3, or it will launch on Sprint shortly after Sprint launches their own LTE network. I say this because LTE requires a SIM card, which means the LTE SIM could go in the SIM slot already on the device (since it is a dual CDMA/GSM phone). Of course, WiMAX requires no SIM, so that's still a possibility, but we don't know for sure.
Finally, I'm not even sure they will have "4g" in the device, because that would be THREE radios in it (1 for CDMA, 1 for GSM, 1 for "4G") which would be quite a lot to fit in the device (though completely possible).
