Microsoft make billions and billions but their long-term outlook is less than stellar so the board and investors want to see decisive correction action. Microsoft's tradition cash cows - Windows, Office, enterprise - are not growing, they are declining. Even Microsoft's biggest supporters are calling Windows 8 a "
disaster", and if Windows long-term outlook is bad, that's not great for ancillaries like Office, nor it's enterprise offerings, nor are they setting the mobile space on fire; Microsoft are insignificant there and lack momentum.
The company aren't in any immediate trouble, they have cash reserves aplenty and businesses are still bringing in a lot of money but it's stagnant. Companies (and investors) want growing businesses, or at least stable, not declining business. I gather Azure is doing good, though.
You can find investor dissent, mostly originating from Third Point and Daniel Loeb, asking Sony to consider spinning off SCE (the entertainment division where PlayStation lives) going back quite a few years. That kind of petered out last year tho where PlayStation received nothing but good press (thanks mostly to Microsoft).
Both Sony and Microsoft released their consoles early, this is evident from the state of the experience on both. A year, almost to the day, Sony announced "immediacy" as being their focus for PlayStation 4 and that it would have suspend/sleep/resume operation like smartphones/tablets. A year after they announced PlayStation 4 and three months after launch, there's still no sign of it. Sony launched waaaaaay early. However I think Sony suspected, or knew, that Microsoft were further behind and thought they'd swing an early launch and start strong, just like Microsoft did with 360.
Now folks want to know Microsoft have a Plan B for lower (or outright poor) worldwide sales.
Because in unscientific terms, they are losing the minds and hearts of gamers. The 360 was a sensational gaming device and the Xbox One misses the mark for so much, but particularly multiplayer and party functionality. Everybody knew it was the weaker device on paper, now it's proving to be the much weaker device in actual games and it's been mired in nothing but negative press for the last 9 months (their reveal was last May). Every game release, which is something to celebrate (new games!!!) is generally shadowed but the game being better on PlayStation 4. What is lacking, is a visible light at the end of the tunnel.
Strategies also have to adapt to the unexpected. If you have a great long-term strategy and it's rolling out as expected, you keep with it but Microsoft's plan faltered before it got out of the gate when the initial ownership/DRM policies met with such a backlash.
Things clearly aren't going according to Plan A. And again, as I said above, folks want to know Microsoft have a Plan B.
