Ok I will start of by saying this is only based on what I've heard from reviews and from watching the quick look.
 
The campaign seems to have almost the exact same set-up as this http://www.giantbomb.com/black/61-8369/.
It might just be me but that's all I'm seeing from all the footage from the campaign. Main character being interrogated and all the missions are essentially flashbacks. 
 
EDIT: Ok I realize a lot of games use this similar style. I dunno why Black stood out the most but it did. Had just woken up when I posted this and hadn't thought it entirely through.
 
The game still looks pretty good but I don't have a decent system to run on PC so 360 is gonna be my only option and on that front I'm still mainly playing Gears 3 multiplayer. I don't know if I will put enough time into it to enjoy the MP much. Since I get paid on Friday I might end up buying this but still kinda on the fence.
