Both unity and rogue looks amazing and a return to great AC games. If they continue like this and keep changing it up while staying AC like, having yearly releases will be fine. Unlike that other game that just plain sucks, imo and should die a fiery death. Plus Unity has been in development for 4 years so if that's not enough time to make a really awesome AC game and it turns out to be worse than AC 4 or even 3 then Ubisoft needs to stop the yearly releases.
