I'm not really excited for AC3, but I'm still getting the game after that ending in Revelations, and I haven't read much of the game yet.
So far, I happy with the game play in the past games, but what I hate is when they add a massive ton of weapons, grenades that I'd probably never use.
I hope we get to control Desmond more this time, e.g. assassinating a few Templars that were following them, or something like in brotherhood and we can get to interact with the other characters.
Otherwise, I'm just following the game because of the story, I kinda want to see how Desmond's story ends. :D
