There's more than just graphics that need to be downgraded if you used old gen. I don't think a game like hitman can be made on old gen without it behaving significantly different.
@Quinn, because you're replying to everyone's post aggressively as if people RATHER have it exclusive on 1 platform over having it on ALL platforms, when in reality, people are suggesting that they RATHER have it on 1 platform, rather than having the franchise die. It's called "worst case scenario".
Nobody is suggesting to make it exclusive over having it on all platforms. So I have no idea why you would even reply to someone with saying it should not be exclusive. Again, nobody is ONLY suggesting that. Worse case scenario.
