I'll not be surprised if the 4th JP will not release around that date in theaters in 3D also. Actually, I hope it's so. Still waiting on Universal to stop sitting on The Creature From The Black Lagoon 3D and the remake.
As long as they clean up the noise, the 3d conversion part will be easy. This is one of those titles you can watch entirely on the teranex without having to fiddle with parallax. It will look great specially the part "warning objects in your mirror may be closer...."
Other titles are very difficult to convert specifically avatar2d , inception and the original star wars are a bitch. On the other hand return of the king is fantastic in autopilot teranex.
