Not Windows 8, but it may look similar.
PhoneArena reports on the rumour that the tablet focussed Windows 8 UI is expected to feature large Live Tiles, much like Windows Phone 7.
Apparently this will be the second, finger-focussed â€œMoshâ€ user interface which Windows 8 will run in tablet mode, versus a more conventional UI for productivity.
They note the OS may have a dedicated gaming focus and feature a flexible 3D interface, as well as a Windows Marketplace app store, and of course is expected to run on ARM chipsets on tablets.
Recent rumours have seen a leaked Dell roadmap which suggests we may see the first public previews of the OS as soon as September 2011.
