Wait, they what? Bing and Surface I can understand to a degree, but they want Microsoft to kill Xbox, one of their strongest brands, and one of Microsoft's only hopes for differentiation? For what, to chase the smartphone game or something?
Some sources say the 360 lost about 3 billion[1] while others that it lost 2.5 billion PER year[2].
The Xbone lost about 1 billion dollars so far (was expected to lose 2)[3]
And it's not just Microsoft that is losing money on these consoles, Sony is in the read as well. [4]
