I'll say 9m. I think it will be the best selling Halo on XB1, and have a similar sales curve to Halo 3, but open to lower sales. While Halo 4 was generally well received, I think a notable portion of the audience was somewhat let down. Additionally, Halo 5 will have a good bit of competition this holiday just from MS published games alone, so I don't think it will sell quite as well as any of the mainline 360 titles.
