I expect an increasingly larger C/C++ codebase to be ported with emscripten and asm.js with decent enough performance (especially dev tools). Currently C++ code compiled with emscripten runs in Firefox only 1.5x slower than natively compiled code [1]. Notable ports can be found at emscripten wiki page [2].
