The biggest tell was how the game was stealth-released, without any fanfare. Now, I'm not an Xbox fan by any stretch of the imagination, but I have to say that the early look at the "cloud-based" destruction was really impressive. Too bad that in the final game, the destruction is still there, but only in the multiplayer side and considerably pared back.
The development hell didn't do this game any favors. For what I've been reading about Crackdown 3, the open world aspect, the wanton destruction, and what have you have been done better in other games already.
