There's a new space sim currently in development by Bethesda that borrows from Wing Commander. It's called Echelon and should be available later this year. Some art is coming together and being released at their website right now. It's looking pretty sharp. They also have a forum where you can discuss the game here. There appears to be a lot of interaction between the company and prospective players. We'll definitely be keeping an eye on this game as it nears release. You can find the official Echelon website here.
