I remember people drooling over some picture of a X06 presentation in Korea and it showed an Xbox 360 hard drive with '100GB' over it. That's when people started getting all "zOMG!" over it. A little after that, Microsoft denied any plans for it.
Then I while later someone took a picture of the Xbox 360 dashboard showing the hard drive and it's capacity. It showed something like "70GB left" or whatnot.
