Where's the excitement in that? Another release cycle is 6 months away, and if past progress is any indication, we'll have gotten Clang C++ to the point where it "just works" for the vast majority of C++ programs . At that point, it will also be 9 months after our first "self-host", which is an eternity in open-source time.
No, 2.7 is the right time-frame for the Clang C++ announcement: we're not done, but we have enough to show to gain attention and draw in contributors, and we have some momentum now from having just announced a successful self-host.

Those benchmarks are trivial to produce, and while we won't have time to further optimize for any of them, we will be able to establish a baseline  in 2.7 and improve from there.
 Compilation memory consumption and compilation time already look better than GCC, along with clearer diagnostics and Clang's other benefits, so we'll have something to say already.
