That would suck and I guess it is possible that MS will jump out of mobile, but I think that the person who wrote that is COMPLETELY misinterpreting what they are reading. If they are dropping support for WP8 but are upgrading ALL WP8 handsets to the next version of the OS, that's hardly the same as abandoning the OS. In fact, they're pretty much making a commitment that neither Apple nor any of Google's hardware partners will actually make.
