The Closure Compiler supports compiling ES6 code already, and can also do transpilation down to ES3/ES5. [1][2]

Google also has the Traceur Compiler which does transpilation of new JS features (ES6, ES7 proposals, and a couple of features that aren't in either) into older versions. [3]

Holy crap, I wasn't paying attention and missed that annoucement... awesome! Thanks, I have no excuse not to try it now.

Poking around, Traceur looks like something to play with and get acquainted, but not for production code just yet?
