Well, duh, it's not a Hitman game anymore. The Hitman we knew is dead. He's pretty much out there on his own now; not working for anyone. Do you honestly expect the game to play the same way? No, it can't; that would make no sense. He's on the run because he's been betrayed by the people he used to trust. Seems like a pretty natural progression of the series to me.
Some people just cannot accept change... Do you honestly want the same, stale Hitman that's been done over and over? This looks new and refreshing. It looks great, IMO.
:EDIT: This is a good read.

What I read in that link was reassuring.
