There's a good article on fiercewireless.com about the NV1.0, NV2.0 phases and their timing:
s noted by Barron's, Wells Fargo Securities and investors met earlier this week with Sprint CEO Dan Hesse and CFO Joe Euteneuer, who provided more details and color on the company's Network Vision network modernization efforts, the first phase of which the carrier expects to complete by mid-2014 (as part of that, Sprint expects to cover 200 million POPs with LTE by year-end). The second phase will be the deployment of Clearwire's 2.5 GHz airwaves on a nationwide basis, and Sprint's management expects to reveal more details on that part of the company's plans "at some point in the not-too-distant future," according to note, written by Wells Fargo Securities analysts J.

Sprint disclosed in July that it plans to deploy Clearwire's 2.5 GHz spectrum using TD-LTE on all 38,000 of its planned Network Vision cell sites in a nationwide rollout. And, due to the weaker propagation characteristics of 2.5 GHz, Sprint will also deploy small cells and other sites beyond the 38,000 Network Vision sites. Previously, Sprint had said it would use Clearwire's spectrum as a "hotspot" LTE network to offload traffic in urban markets.

I wonder who they mean when they talk about network sharing? According to some in this forum, they hate Dish and Ergen. Yet, he's the only one one that does not have his own network. Did they forgive and forget?
