I'm with AC...I'm starting to think that a Mini update is the last thing Apple is working on.
It's probably on the list with these other products:
G5 PowerBook
iPhone 3G w/SBG slot (stick of bubble gum)
iMac that changes smell with what's on your screen
iPod Classic w/boomerang attachment
MacBook that transforms into an iPod (to coincide with the Transformers 2 movie release)
