This is exactly why toy companies don't want to tie into video games. The gaming buisness is very unpredictable, and games can get delayed months or years at a time. Hollywood movies stay on tight schedules for release, so it's easy for toy companies to coordinate their business.
These delays could totally screw up the whole year for Lucasfilm. TFU was supposed to happen in the spring, an Clone Wars in the fall, now they'll both (maybe) be hitting at the same time, causing a glut.
