I didn't say they weren't. I imagine the project needs lots of help. Is there an ETA? Will the ports be kept in sync with the Windows versions so we don't need to wait years for updates? It's a lot of work.
I think their goal was a year for everything under .Net to get ported but I don't know off hand. You can already use it via Mono if you wanted to play with it today.

It's all being opened sourced. Every week Microsoft open sources more of their .Net platform and language tools. It will be compilable on all platforms. So yes.
