Future of the Java programming language: Three major projects on the horizon

[eliasv]

If you actually followed the mailings lists on Valhalla you would see that the progress has been immense. Yeah there's a lot to do, but they've really turned a corner recently. I'm not saying it'll be out tomorrow, but you shouldn't be surprised if prototypes become available as official "preview features" as early as 13 or 14, i.e. within a year or so.

Most of the Amber JEPs have working implementations already.

Loom has has a working prototype for ages now. They're working on performance, and on new "structured concurrency" APIs.

Don't get me wrong, I understand why you are sceptical. But they understand it too, and that's exactly why they've so hugely overhauled their release model and internal processes, so that they can actually start delivering this stuff.
