Assassin's creed revelations collectors edition?

Is it worth getting.????? last time I went too the midnight release of assassins creed brotherhood on a school night and got it collectors edition and then what made me mad was that the people who didn't get it collectors edition got the same chacters and maps as me like a few months later for only 15bucks. So is revelations worth buying collectors edition so I can get exclusive characters and maps or should I just get it regular and see if they will come out with a dlc and maps ?
