Windows 8 arrives later this year, and we're already getting some huge numbers from Microsoft CEO Steve Ballmer on predictions of sales. In a speech to the Seoul Digital Forum in South Korea, Ballmer has said that up to 500 million users will be on a Windows 8-based device by the end of 2013. Ballmer added:

It's really, in some senses, a dawning of the rebirth of MS Windows... It's certainly the most important piece of work we've done.

Ballmer also teased that Microsoft will "soon" launch a version of Skype for Windows 8. This could be part of, or arrive close to the Release Preview of Windows 8, which is expected sometime in teh first week of June. Ballmer also talked about cloud computing, predicting that in a few years, there'll only be a few companies that will dominate that industry, he continues:

The number of core (cloud) platforms, around which software developers will do their innovation, is not ever-broadening. It's really a quite smaller and focused number -- Windows, various forms of Linux, the Apple ecosystem.

Will you be getting Windows 8?
