According to documents posted, a lawsuit between and 3D Realms regarding use of the Duke Nukem IP that was filed in February 2014 has finally been settled.

Unfortunately for the development team, Gearbox had already nabbed the licence from 3D Realms in 2010, in order to develop 2011's atrocious Duke Nukem Forever. Gearbox accused the firm of attempting to “privately convince others that the sale never happened”, claimed that the game encroached upon their intellectual property, and filed a suit.

None of the parties involved have commented on the case. We'll keep our eyes out for any further information.
