It's highly unrealistic that a 53 year old man could be this agile and the fact that he actually managed to employ feats of agility like the ones in the trailer after sustaining an arrow wound to the shoulder proves how little faith Ubisoft had in the character to begin with. They obviously want to milk him for what its worth, extending his story as much as possible. Look, I enjoyed what you did with the first game. Visiting locations most games never even give a chance was a welcomed change. However, you're no longer even trying to make the world unique. AC2 addressed a lot of the problems AC1 had but as it stands, you're no longer attempting to refine the formula. You're milking it.
I understand Ezio is a popular character and I understand Ubisoft never expected him to become the icon that he is today but by this point they're giving us to much time with him. They're not innovating at all and they're reusing the same mechanics they used in AC2 with very minimal changes. The Assassins Creed series, at least to me, was about innovation. As it stands, Ubisoft is not innovating, it's rehashing the same tired old shit.
I'm not saying this game will be bad but once you look at it from a different perspective you're just playing Assassins Creed 2 except now you get to visit a reskinned version of Rome. You also have to pay 60 dollars to do so.
It seems Ubisoft has run out of ideas on how to innovate with the series so they're just stalling now.
