I am kind of in this camp as well. I understand there is nothing much now to replace js on the client (kind of like js as an assembler language so stuff compiled to it), but I am ready for something better. But also, it is 2013, []+[] should stop being equal to ''.

Also think if anything or anyone is going to make a change it would have to be Google. Can't image a small company out there coming up with a new browser with a new language. It would have to come in Firefox or Chrome. So I am excited for Dart.
