Lifetime to date sales for TR2013 are only at 1.86M on 360 and that's a platform with well over 80M in install base, I think this game will be lucky to break past the 250K mark before the end of the year on it's own sales (as in software selling independent of bundles).
If it's heavily bundled maybe it can break a million by the end of the year, though I'm more likely to believe it will sell closer to 750K with bundles.
The major mulitplats will be moving on PS4, including Fallout 4, Battlefront, etc and people know that they can get RTR a year later on that system, probably for a lot less than it will be at launch, with full DLC and improvements.
Alternatively the existing 360 owners can buy it there or PC gamers can wait a few months and buy it in the spring.
Fall is going to be tough, TR2013 released in March first time out, so it didn't have this level of competition that a November release will bring.
