When has MS not been about gaming as a core aspect of its business? Even before Xbox gaming was an important aspect of Windows, and it is a vital component of phone and tablet business now. The Xbox brand is now core to the gaming aspect of Windows, so even if the hardware disappears the Xbox brand will remain.
I don't necessarily see this as a vote of confidence or strong commitment to the Xbox gaming console. But it would take Xb one to have a truly disastrous generation (sub-20 million) for MS to not produce a 4th console.
