--how is it SO far-fetched that they have a battle on Geonosis? It's still a planet, it didn't just get blown up or completely forgotten right after the clone wars ended. It is still a good place to build a base and have a battle. Besides, even if there wasn't a battle on Geonosis, it's still possible, it's not like every last little thing has to be exactly in place, a lot of things are, but Geonosis is still a logical spot for a battle. 
Curses, foiled again!
