Sony didn't give the rights back. Sony still owns them they're allowing marvel to use them.Lol at people thinking Fox is happy at making 400-500 million mediocre money just to keep the x-men rights
Sony amazing Spiderman made more money than any other fox x-men film(I think besides deadpool) and still give Marvel back the rights
Keep thinking Fox won't smarted up
2nd,the x men films have been a huge success so keep dreaming.
Sony was in the middle of scandals and the company was floundering losing money everywhere. Fox doesn't have that problem.
