Actually both WiMax & LTE share almost the same technology (OFDMA based PHY and IP based core).
I believe LTE will be the dominant technology which most Cellular operators will adopt as the GSM/UMTS/HSPA successor.
However there is certainly a room for WiMax as a niche technology. WiMax will be in the market before LTE (but not before HSPA+) and has a great future within developing countries and small operations, such as municipalities etc. More over Intel will probably continue to push WiMax so it must help.
