IGN among other outlets believe thats exactly what it'll be. It'll be interesting to see what numbers ACIV does, but these games that are having cross gen releases are seeing their sales take a dip due to what most suspect are people waiting for the next gen versions. Games like Watchdogs and Titanfall are being marketed MUCH more heavily towards the new systems than they are the current gen systems.
If this is accurate and Titanfall isn't coming to PS4, its a decent coup for MS, no matter how badly PS4 fans want to deny it. Its no game changer or anything of the such, but if Titanfall comes out to be the title most think it's going to be, that's going to be a big franchise for MS to have. Even going forward, if more Titanfall games come out and release on other consoles, it'll more than likely be associated with Microsofts Xbox One. We've seen it with series like Bioshock(more sales on 360), Mass Effect(more sales on 360) and Metal Gear Solid(The HD pack sold much more on Playstation 3).
