I guess they had to do it because of the amount of leaks; Microsoft published a video showing us the new (codename) “Metro” UI for Windows 8. This will be the primary way to use Windows 8 on touch enabled devices, such as the ARM enabled tablet PC. I have to say, based on this (and this is probably too early to be 100% sure), Microsoft may have hit a grand slam.
This is the first of many promised videos. I can’t wait for more. Note the comment about multi-tasking
This video appears to have gone viral.
