Here is my prediction for Windows 8.2, if that is the next Windows after Windows 8.2
More settings will be moved into Modern
More basic Windows programs like paint will be put into Modern
The clock on the taskbar will be eliminated in favor of the clock when you bring up the charms bar.
A new default desktop theme will be introduced
A lot of apps will be refreshed.
More improvements for the start screen will be added like personalization etc
Windows Media Player may be eliminated in favor of the Xbox Videos and Xbox Music (I hope not)
The battery and volume taskbar quick settings will be 'modernized' like the wifi is already
the desktop will be totally hidden in the next version of Windows but desktop apps will continue to work but in a full screen type way.
These are just my predictions of course, and the next Windows could be anyone's guess.
