No MS are just more focus on their first party properties.
This is the problem. Sony just made Microsoft look like they cannot make first party themselves. Anything major and successful new IP they've created as of late has been second party at best. I told everyone that Sonys first party takes about two years before it gets going and I want my money now.
This. Microsoft is doing a great job securing exclusives early in this gen like they did with the 360.
But very few of them are first party as only 5 of the upcoming exclusives are developed by studios owned by Microsoft (Gears 4, Halo 5, Forza 6, Fable Legends and Sea of Thieves). If people could see that Microsoft was funding new internal/in house studios that would develop several quality exclusives throughout the gen they'd be more convinced (at least I would).
Seeing how the great exclusives like Kameo, Dead or Alive, Project Gotham Racing, Dead Rising, Saints Row, Gears of War, Viva Piñata, Crackdown, Blue Dragon, Lost Odyssey, Ninja Gaiden, Fable 2 and The Last Remnant all stopped in 2008, many fear that the same thing will happen with XB1.
