Well the biggest exclusive games coming this year, that seem to be up your alley are now Halo 5 and Rise of the Tomb Raider. In terms of last year's exclusives it is a toss up between Infamous and Sunset Overdrive. Both games are great (well I know inFamous is pretty great because I've played it, and I've heard SO is great but I've never played it).
Is P5 definitely coming to the West in 2015? If you are a major Persona fan that does come into the equation.
If you are angling for a 2015 purchase Xb one is probably the way to go, unless Persona 5 is a deal breaker. If Persona 5 is not a deal breaker then 2016 would be the year to get PS4.
