I looked on the status page and it seems like things are moving along to the ~1.0 release, but as an outsider I can't gauge if that's three months or a year.
I'm mostly just really excited for this at there's a great deal of it (Deno) that makes a shitload more sense to me than Node (module loading is one, $HOME/.deno/bin is another); and being so heavily integrated with Rust appeals to me in a big way (I actually understand Rust, but C++ always leaves me just instantly mind-fucked).
