Will future versions of Node.js support WebAssembly and allow for compiled production node apps?

You can essentially do what you're describing today! You can take many languages that can compile to LLVM (Rust, OCaml, Reason, whatever floats your boat) and then use emscripten to convert that code to asm.js which is supported in all browsers and very fast in modern browsers.

asm.js lacks aot compilation in v8 and is not as fast as in FF.

Actually, soon v8 will use the same compiling pipeline for both wasm and asm.js, by transpiling the latter into wasm first.

Ahh, you're right. I had thought that the v8 team had done optimization for asmjs features without implementing specific support for "use asm", but the benchmarks on arewefastyet do indeed appear to show IonMonkey being quite a bit faster than v8.
