Sounds like a major drought is coming (Answer from Jedi Temple news)
A. The EU wave that was shown at Comic Con will be the last of the red/white Legacy series for Spring 2010. The Legacy-type basic figure line scheduled to launch next Fall will follow a wave theme to ensure that each movie gets one focused wave, then we will change to a non-wave based system. The way it looks currently, there will be Fall 2010 waves for EpII, III, V, and VI (not in that order) with EpI and IV getting waves at the beginning of 2011.
It's going to be a long summer again........
