Heh, let's see...all that's needed to cover the OS upgrade are the OS to be sent to the factory (already done, probably the moment that 8A428 got the go ahead, they probably started switched to it,) stickers to cover up the spots necessary to signify the new release (screenshots already printed probably 3 weeks before GM, and new text too!) and websites are known to be purposefully behind schedule so as to prevent a rush of ordering until they are ready...soooooooo, think twice before pushing the button next time, 'kay?

Just because a source says it doesn't come with it, doesn't always mean it's true, especially in the case of improvements and upgrades.
