I seriously doubt Rise of the Tomb Raider is going to be announced for the PS4 a year in advance of the "Holiday 2015 Exclusive" deal with the X1. With all the talk lately of Ryse possibly being on PS4, it wouldn't surprise me if that happens. Which wouldn't be a huge deal for the game itself but would represent an increasing problem for Microsoft in that the X1 is getting an image as a console where most exclusives don't stay that way despite what they claim initially.
