Sprint does not publish a complete schedule far in advance. The best information is found at the S4GRU.com website, which is unaffiliated with Sprint but very well informed.
No, that link to the Sprint site does not cover Sprint's Network Vision rollout, which is a total network rebuild and includes the new LTE service. The Sprint link above covers only "band-aid" upgrades currently scheduled for Sprint's legacy network. Sprint does not publish a complete schedule of the NV project or its LTE buildout. The only place to find a projected schedule for that, albeit unofficial, is on the S4GRU.com site.
FYI, today Sprint did release a list of cities, large and small, where deployment work is underway. But that is not a schedule because there are no launch dates.
