Family Guy may strike back
According to James Hibberd at TV Week, the team behind the Family Guy Star Wars episode may take a crack at parodying The Empire Strikes Back next year, possibly even having it be an annual event like The Simpsons Halloween specials.
One good thing about parodying Empire is that they can touch on the Han/Leia romance since the roles are played by Peter and Lois Griffin, respectively, who are married on the show. The producers weren't allowed to touch the Luke/Leia kiss because they wanted to play on the incest angle (which would have worked doubly so since Luke was played by Lois' son Chris). This logic may also explain why Princess Leia is played by Lois rather than Meg.
In my experience, the entertainment business usually gets caught up in anything that is even moderately successful and automatically thinks sequels. It makes sense, considering the good ratings the episode got. However, unlike the unlimited potential for The Simpsons Halloween, they have only a limited number of movies to parody. In five years, they'd be done. What would they parody after that? The Ewok Adventure?
