I kind of wish D would pick up. It's very familiar and clean, and a few things are remarkably easy and fun to do.
Though reading through issues and threads about it, and maybe high performance programmers using it have more than a few things to say about the state of the GC. I'm not sure if that's changed or not. I've only dabbled yet.
I'd like to see a community grow around it. It, or something like it, seems to me like the path a modern, low-level language should be going. It's not there yet, but in terms of the feature-set, optional safety, syntax, typing, etc, it's an attractive space.
