The roadmap is too short on technical details.
How they are going to achieve 6x throughput at 64 sockets in 2013? The only possible way I can think about is by commercialization of SPARC64 IXfx supercomputing engine. But then, how are they gong to reach 1.5x single thread? SPARC64 IXfx would probably be lucky to reach 0.8-0.9x of single thread performance of VII+.

Now, looking at details of SPARC64 IXfx, it does not look like it is capable of 6x throughput either.
The low hanging "throughput" fruit of Sparc64 architecture is 3-level cache hierarchy with L2 cache either private per core or shared by 2 cores. SPARC64 IXfx still does not have it.
