On the game's dedicated forum, one of the members who appears to have some inside knowledge (and has made plenty of accurate guesses before) speculated that the new, mystery publisher might be none other than Microsoft Game Studios themselves.
If so, it's entirely possible that they are just sitting on the release, waiting for an okay from the courts, and will make it live as soon as the ruling goes through. This would also mean it would be much easier to stay current with future releases.
FarSight clearly has made some missteps (and the lack of a PC version is laughable, though publishing with M$ should help with this too) and I, too, am frustrated, but I think there's a good chance that in the next month or so they'll be caught up on all platforms.
