Yes I meant the standard produced by TC39, of which Ecmascript 6 is the new version. My apologies for loose use of terminology.
I would be somewhat happy if ES6 was finalized next month, but if it slipped (again) I would not be surprised. You'll also have to forgive me if I am skeptical of claims about the increased speed of future standards. The burden is on TC39 to prove this to me and I reserve the right be skeptical based on prior evidence until I see otherwise.
ES6 features are already shipping in many browsers. http://kangax.github.io/es5-compat-table/es6/
Uhhhh TC39 meets bi-monthly. If you meant ECMASCRIPT 6, it's targeting finalization next month. Furthermore, future releases are set to be much, much faster than previous ones.
