I expect he will be denied bail if they can show the evidence against him is strong enough. Even if you have enough money, that’s just not a guarantee. They don’t set the bail at $50mn or something, it’s just not an option offered.
The boring but probably correct answer is he never breathes free air again, and his best case scenario is avoiding the death penalty.
Absolution was a pretty good game (in my opinion) but it wasn’t a very good hitman game. If it had been a standalone franchise with different characters etc it would probably be thought of as a very good game of the time. For example, the bit where you’re tracked by the cops for several levels had a great James Bond/Bourne Identity type feel.
