Forget about sprint expansion of wimax. They are implementing lte.
That's as good of guess as any. However, there is no way to know which way Sprint is going at this point. It's conceivable that they finish WiMax rollout in primary markets with the LTE rollout. They may even do secondary markets too. They have so much 2.5GHz spectrum, that they can conceivably do both with the Network Vision upgrades.
And as you point out, they may stop WiMax expansion altogether. Not a single additional WiMax tower. Or, they might just finish a WiMax build out to 100% in the cities they already serve.
Sprint is being very tight lipped about it. Hopefully this will be one of the mysteries solved at the October 7th Meeting.
