If I were you, I wouldn't worry too much about Absolution. Everything we have seen so far, began with the previous games but they just evolved in Absolution. Absolution will also be the first game to showcase why 47 is indeed a superhuman to a point. But all that doesn't mean it's gonna be dumped down.
The previous games had a major flaw that made them really easy, which was the AI. They were also too shallow. Now it seems that they're gonna fix that, so hopefully, it will compensate for the new powerful stuff that 47 is capable of.
BTW, the developers confirmed that the silent assassin rating will be back in Absolution and it will be harder to obtain it because of the way the AI acts and the way the guards are positioned. So, this pretty much confirms that Absolution can still be played patiently to achieve the Silent Assassin rating.
Afterall, Hitman was always about replay value more than anything else and it seems like that focus is still on for Absolution.
