You know, the VA who is doing the voice in this video sounds a lot like Cole from Infamous 1. Perhaps this is why Sucker Punch has a different VA for I2.
As for this game, based on this video I am not sure what to expect. Sounds like the game is established on today's world and events (he was talking about 9/11), so perhaps the game is going to be geared for more realism and simulation style gameplay/story.
I will keep my eye on this game, but amongst the dozens of other FPS games releasing this year, they are really going to have to stick out as something unique and special to grab peoples attention.
