Well now that depends on how 47 bows out, if he decides he has exacted enough revenge on Providence and then retires to the canary islands to live in luxury then it does not matter as much. If he is shot in the back and then nothing then people will be really angry (Except for me depending on how they would handle it and that would be hard to do).
I hate it when people compare 47 to god.
I mean sure, he is great and all, but he ain’t no 47.
David Bateson is 47, unless he has twin brother(s)(afaik he has not). BUT if Mr. Bateson unable for Hitman then IO should find someone else and make him/her another ICA agent.
Or they could make a game like Half Life: Blue Shift.
