The JS VM idea is really interesting - because it frees a language from having to have basically a one-to-one mapping between the new language and JavaScript a la CoffeeScript. So I'm going to update my guess: I reckon Dart will be a tweaked version of Newspeak natively supported by V8 (server and Chrome browser), plus a JavaScript VM for running Dart on non-Chrome browsers. More of a guess, but I imagine it might come with its own node.js-y framework with perhaps some interesting Seaside-style continuation approach and/or Lift-style view-oriented approach...
