I'll go company by company
Sony: The only games I'm really interested in is Naughty Dog's next game after Uncharted, The Order 1886, and Infamous Second SonMicrosoft: Platinum's exclusive game, Sunset Overdrive, and TitanfallNintendo: X, Zelda, and Bayonetta 2, Smash and Kart
My current order of system preference in terms of exclusives is Wii U > PS4 > Xbox One.
From Nintendo I have New Super Mario Bros U, Super Mario 3D World and Pikmin 3. All great games and Mario Kart, Smash Bros, Bayonetta 2 and are all looking like excellent additions.
For the PS4 Infamous: Second Son looks great, The Order 1886 looks interesting and I'm looking forward to the next Uncharted.
For the Xbox one I don't care about any of it's big three, Halo, Gears of War & Titanfall. Dead Rising 3 looks interesting but not great and I don't know much about any other exclusives for that system at the moment other than stuff like Peggle 2.
