Why are people surprised at the news that he probably won't defend the MW belt? He said in interviews before he came back that he had a plan and knew what he wanted to do... It's simple. Come back and beat Bisping and get a second UFC belt further cementing his legacy and giving him leverage. Then vacate the MW belt and fight for the WW belt. If he wins that then I think he would want one more fight against Conor for one more big payday before he sails off into the sunset and retires.
