As much as the 3D is hyped in general, it tends to be a fad that comes and goes every few years with films. Until the format is more immersive and consistent I don't forsee Star Wars getting released in 3D on a home video format any time soon. There seems to be a huge gap in quality presentation with 3D. Some films look great, like Avatar, and others look terrible, like Clash of the Titans.
I don't doubt that it will be released on a 3D home video format, I just don't think it will be soon. Most home theater owners haven't converted their systems over to 3D yet, and in my opinion, the consistency of quality isn't up to par. I have yet to see a 3D home video system that blew me away. They're probably out there, but I just haven't seen one in person.
