The behind the scenes stories about this game will be very interesting. They've clearly put a huge amount of work into trying to wrangle a troubled project into something fun. Open world games go off the rails very easily, and are extremely difficult to hammer into something cohesive.
The key will be whether the game is fun. I think some people want Crackdown to have some Game Awards-bait story or something like that. Wanting the game to be some sort of "prestige" Microsoft exclusive designed to make people jealous. It's not that sort of game. It's Crackdown.
The difference between Saints Row and Agents of Mayhem, for example, is that Saints Row was fun, and Agents of Mayhem was kinda... not very fun. Crackdown 3 needs to be more of the former, less of the latter.
