Wasn't there supposed to be a Gothic II Xbox version at one point?
Gothic 2 was indeed intented for xbox, but never materialized. Xbox was at an unlnown status back then, they could not predict would be so huge, but now things are diffrent, with games like Oblivion beeing the spot light for xbox 360, it would make perfect sense to release it for xbox 360. That way we would not have to buy 2000$ pc's to play it, and we would avoid the hassle of pc gaming like crashes/bugs/patches/drivers etc etc
Here are some facts about Gothic 3 coming to xbox 360
1. Jo-wood has spoken of gothic on consoles plans
2. In an quite old interview about gothic 3, developers said they were thinking of a xbox 360 version, but only after pc game is ready
3. Gothic 3 uses gamebryo 2 engine and speedtree, as Oblivion does and the port to xbox 360 would be really much easier than with any other engine
1. The bidding for publishing rights is indeed a rumor, but the game is not as popular as to create random rumors about it, so the possibility of this beeing true is really high
