I thought Arkane (the guys that did dishonored and others) was working on Prey 2 now? Still, Human Head's version will probably never see the light of day, which is sad. What's sadder is the way Bethesda/Zennimax treated them. They really got screwed over.
That PotC game doesn't look very good... The only Pirates of the Carribean game I actually liked was the one by Akella, which was originally going to be Sea Dogs 2.
