It looks like MS disabled that ability to sync WMP11 to removeable storage cards. Synching to storage cards worked in Beta 1 & Beta 2 but feature disappeared in final release. I love the new interface, but I'm contemplating reverting back to WMP10 to get back syncing functionality.
A thread in the MS Windows Media Forum seems to confirm this. Read the thread "Recognizing Storage Card".
