WiMAX in theory can be upgraded and go up to 1Gbps. LTE can only do 300+ Mbps.
Anyway, both WiMAX, HSPDA and LTE are complimenting technologies.
HSPDA and LTE can provide nation-wide coverage + international roaming (cell phone technology).
WiMAX on the other hand, focus on Taman/City wide coverage (like Wifi).
There are 2 different technologies. But both are important and has their advantages.

Actually there are no differences when it comes to coverage between LTE and WiMAX. You still need base stations to provide coverage on a particular location. What's so special about LTE can provide nationwide coverage where WiMAX can only focus on small neighborhoods? Aren't they the same? You still need base stations. It depends on how much you have in your pocket that drives your business model (cover the entire nation or just start with major cities).Anyway, both WiMAX, HSPDA and LTE are complimenting technologies.

For a green field investment, there is no difference in financial investment when it comes LTE or WiMAX. The only reason LTE is 'popular' is because conventional telcos have to work with their legacy (circuit switched). LTE PROVIDES that option and while they move to IP-based communications. For a green field investment, they don't need to be constrained with these legacies.
I don't understand what is the technical superiority of LTE over WiMAX. They both use the same modulation, very similar radio infrastructures, etc. Another reason the big guys choose LTE besides giving them the choice to work with their legacies is economies of scale. It drives equipment costs down. Companies and ODMs move where big guys move. The ecosystem shifts.
By the way, the future is IP-based communications. LTE is the future but WiMAX is the future we have today and ready. WiMAX 802.16m is on the way. By the way, does LTE have QoS? ;-) The standards for LTE is not yet ratified. Still open for changes.
