I don't have a clue of what type of investment this would take and who it is that is putting it up, but if Lucas is willing to share the back end with investors or the studio I can't believe that one of the major networks or even a cable network with deep pockets would kill for the chance to own a piece of this. I can't imagine it is expected for this to do anything but rape all competition in whatever time slot it goes to.
Money in movies just doesn't exist in television, however this is a franchise that doesn't loose money, and since the creator has resisted the fans demands and not gone crazy just putting out everything possible to cash in. There is still plenty of room for films or shows or videos.
Shit, he could go straight to video with this and charge a fuck ton and sell a huge number. People will pay for star wars, I just can't believe that it is money that is holding this up.
