Xbox exclusives? Yes. Microsoft exclusives? No.
I know some fans want to make a federal case out of Microsoft spreading the wealth, so to speak, across PC and Xbox - but is it that big a deal? Let's be honest: most of the people saying "I was going to get an Xbox for [insert title] but now forget it" or "No need to get an Xbox now!" probably never intended to purchase one. In this culture dominated by lists and pissing contests, Xbox losing "exclusives" is more another chapter in the neverending console wars than it is a death knell for Xbox. By moving its games over to Windows, Microsoft may lose some hardware sales, but it could potentially increase its software sales by a large margin. And who knows, maybe some of those Windows gamers will like what they play, and choose to invest more thoroughly in the Xbox ecosystem.
Also, if we're continuing with the honesty angle: exclusives are important but not THAT important. The best-sellers on Xbox and PlayStation are Call of Duty, Grand Theft Auto, Fallout, and Fifa.
Lastly, the line-up of Xbox "exclusives" that so many are mocking as insufficient is, in reality, more than sufficient for a lot of folks - myself included. To be perfectly frank, the first-party games arriving on Xbox in the next 18 months are more attractive than the first-party games landing on PS4. Sony secures a lot of great exclusive third-party content, but it's suffered lately in the first-party department.
