Today the Unreal Development Kit (UDK) was released making it possible to create standalone games using Unreal Engine 3.
Of course it's questionable if one could use it for a DK-like game, though the idea is quite exciting. Bluto's models could be used with extreme details
Nevertheless it's a great opportunity for fan projects out there. Maybe other developers like Crytek will follow this path
