Who do you think is making all those mocksup?! It's the power users who want the metro UI for the desktop; it's the power users who install rainmeter for the metro themes. Microsoft is scaring off the power users more by leaving the desktop in stasis than by any rumors they'll give it a designer makeover.Baby steps. Look at all the people freaking out already over just the new Start Screen and it's drastic change from the start menu. The main thing they've been able to point to to calm down the "power users" is that the desktops remains pretty much just as we've all come to know and love. If they just completely revamped the desktop style to something like the above pictures, I'm almost positive there would be a giant uproar ("MS is changing everything! the sky is falling!!") even though it looks incredible. I think once they nail down the Start Screen and getting people used to it, that's when they'll start messing with the desktop in Windows 9.
