Assassins Creed Black Flag

So...I know that not many people read this but hey...I'm going to try...

So Assassins Creed Black Flag is coming out. What do you think, will it be better than Assassins Creed 3?
What does it need to be better than AC3?
I'm not sure about what to think of AC Black Flag yet, I don't know much about it, but I will definitely be taking a look at it.
