IO Interactive have released an open letter which states the future of the Hitman series. In the letter they have confirmed that they are building the next AAA Hitman game on next-gen consoles and PC.
In the next game you will experience a globetrotting Agent 47 at the prime of his career – the apex predator stalking his prey across the world, with the support of his long-term handler Diana Burnwood and the whole of the ICA.
Contracts Mode is back – you will be able to create and build challenges by experimenting with the large levels and possibilities within them. And of course, you can share them with the world and challenge your friends or foes to complete your hits. Your rules, your Contracts.
IO Interactive have also removed 47’s magic pockets. They haven't elaborated on this, but that can only really mean that you can't bring an unrealistic amount of weapons out in to the mission without a place to put them. It will probably be far more difficult to hide weapons now, too. You will probably need a holster or pocket for each item. That, or 47 will be getting a style upgrade with a briefcase or backpack, but that is far less likely.
There will be more information soon.
