Is anyone else getting excited about the someday-soon release of ECMAScript 4, which will equate to JavaScript 2 in standards-based browsers?
It's slated to be much more supportive of object-oriented programming, with classes, iterators and generators, built-in JSON handling, optional static typing, and other improvements aimed at increasing performance. Also, bug fixes!
Read the overview PDF or the spec wiki, or check out the feature spreadsheet.
Impatient types may prefer to just anticipate JavaScript 1.9
