Honestly, I hope they leave the Klingons out. They've been done to death and like I said there is so many possibilities that I hate to think they will just redo the same of stuff, like the idea of Del Toro as Khan, that rumor really turned me off to the idea of a new Trek movie if that was going to be the story, same thing applies for the Klingons for me.
