Yup. You read well. Gothic 5: Aeternus will be coming spring 2012 for the PC and Xbox360.
Gothic 5: Aeternus will be a reboot of the Gothic series. The story will take place in the Mordrag world 500 years after the events in Gothic 4 and will be centered around humanity's desperate last stand against an alien invader from a different dimension. According to the official press release, the game will be open ended and there will also be a savegame export system, kind of like Mass Effect. Also, the old skill system from Gothic 3 will return, but more evolved. DreamCatcher has not yet disclosed the name of the producer, but they have stated that the game has been in production since August this year.
