Prequel Watch has an article featuring a fan discovery that could prove to be something
interesting, and he found it in Star Wars Insider #65. 

"The latest issue of Star Wars Insider has a fold-out map of the galaxy. Well, I was looking over the map, and there's a planet next to Coruscant called Caamas. Underneath the name, it says the planet Caamas was destroyed 19 years before the Battle of Yavin. This is when Episode 3 is going to take place. You think the planet Caamas will play a pivotal role in the Clone Wars, or perhaps the rise of the Empire?"

Things that make you go Hmmmm... This would certainly be an interesting development if a planet gets destroyed in Episode III as the Empire is on the rise. 

My personal opinion is that we will not see Caamas or any planet destructions. It would take away from the horror that Princess Leia had when Alderaan was destroyed. Up until that point, no one thought that a planet would or could be destroyed. Lucas may refer to Caamas as he did Dantooine. We never saw Dantooine, but we knew there had been a Rebel base there. Maybe Caamas was a stage for a major battle during the Clone Wars and will be referred to in a conversation. Again, that is just my opinion.
