If Google submits Dart to an independent standards body that has a governance model that includes other interested parties e.g. Mozilla, Apple, W3C, and doesn't make Google king, and if Google agrees to adhere to the standard and not just rush ahead with a de-facto standard reference implementation that people write anyway to because it's in Chrome, and if other browsers widely integrate Dart, then it would no longer be proprietary. Until these things are achieved then it is absolutely proprietary and claims to the contrary are based on a PR position about a possible future that could easily be de-prioritized or never come about. I could easily see developers jump on board this 'soon to be standardized' language, only to see an announcement that 'Other vendors didn't join up, so we have been forced to go it alone' from Google.
