are these things available?

If you go into their online store (I created a user account named "[email protected]" with a password of "foobar" just so I could browse there, you can use it if you want), they say "in stock".

So yeah, I guess they are available.

They seem interesting, but they have the same restrictions as the Neo. Deep car cage prevents in-dash mounting for many cars, 3.5" drives aren't suited to mobile use, etc.
