As much as you may not like it, if the XB2 performs worse than the XBO, it is inevitable. Investors, nor Nadella, are going to want MS to continue to release HW if it continues to underperform. It's why they are pushing PC and this Live expansion. If they can't rule the console space with their own HW, they'll try to do it with SW and online.
As long as they’re making money, I highly doubt investors care. Didn’t Sony sell like 90 million or so PS3s? And yet it lost them money?
The reason you keep predicting Microsoft to exit and keep coming up wrong is you’re looking at it from a sales scoreboard point of view when that’s mostly irrelevant. Also its not surprising Microsoft is branching out into services and other stuff, every company is, even Sony and Nintendo.
