As you say, WeakMap is a feature of the upcoming EcmaScript 6 standard, and hence will be supported by all browsers sometime soon. (FWIW, Chrome also has supported WeakMap for a while, albeit you still need to turn on the 'Experimental JavaScript' flag on the chrome://flags page. And IIRC, other vendors are working on it already.)
But yes, WeakMap is carefully designed to not make GC observable, so it cannot implement weak references. Weak references are on the agenda for ES7, but that will take another two years at least.
