If Titanfall will be a big success, this would be too expensive. We are talking about some hundred million less revenue if it is only on one console and Ps4 has a bigger userbase and will probably have a bigger userbase. If Xbox One would have a decent sales advantage against PS4 I could believe it but not if PS4 will have like 2x as many sold consoles (something I obviously don't know)
If anything it will be much easier for Sony to pay for exclusivity deals this gen since developers won't lose to many sales without an Xbox One version.
