So basically, they are not making a Hitman sequel.
Mmh. There's basically two options here, they either make it a max payne to court the dudebros, or they go to hitman 2 and make it so that you can essentially go through all the levels shooting, you just get a worse rating. At least that's what I remember of the progression of the series, 3-4 were less forgiving in that sense.
Still, I don't think the expression I used above has ever been more fitting (ok, maybe deus ex iw is close) than here.
