Well I believe that Windows 8 will address two main points as the situation is quite different compared to the time Windows 7 was designed. The first point is the mobile devices in the enterprise. As some people already mentioned tablets and smartphones are almost everywhere since the childhood of the newcomers. The other point is the Cloud.
So my expectations are with Windows 8 MS to bring the desktop capabilities and the established and emerging Cloud services wherever we can took our smartphone and tablet.
Of course there are still some licensing issues and questions about the Metro style apps, but this is actually a turning point and it will take some time.
