Most Likely to Occur
WebAssembly.

Less likely
Chrome manages to convince everyone to implement a browser filesystem API. If that happens, then the web is unleashed even more. But haven't seen other browsers play ball on this one.

Wild 'Fantasy Land' Guess
JavaScript moves beyond JIT in Browsers. Browsers begin to allow TypeScript to compile some hot code that Browsers can run. Chrome (v8) already does this (nothing to do with TypeScript) but there's a start-up cost and developers have no control over it. The idea would be to do it at build/compile time. Not all your code is optimized but some of it is. So people could still push normal code if they didn't care about that.
