Plot are usually simplified for movies. That's a given for movies. So they could cut/simplified out a lot of stuffs like getting evidence against Saren, but the battle on Citadel is definitely a must if they need action. Or yeah, they could go the same direction as the novels (although I have yet to read the novels as it is not available in my country) as there's a lot more possibility with that route.
