Dashboard advert shows stand-alone 250Gb HDD for Xbox 360

Looks like Microsoft plans to start selling a stand-alone 250Gb HDD for Xbox 360, according to an advert of sorts posted in Spotlight section of the Dashboard.

The ad reads that it will be made available at "participating retailers" and while it says you can "purchase one today", the link to the Accessory Store for Xbox 360 does not have it listed yet; however, Amazon has it up, with a price and date to be determined.

So much for the 250Gb HDD only being offered in bundles.

Thanks, Joystiq.
