What happened to the W8 USB hardware requirement?

So a while ago Microsoft announced the hardware requirements for Windows 8 tablets. One of those requirements was that they had to have at least one full USB port. So far most of the Windows 8 tablets announced at Computex do not have a full USB port on the actual tablet devices themselves.

They all appear to have USB ports on the keyboard dock sections but this shouldn't count; it isn't very practical if you have to dock with the keyboard section just to plug a USB stick in to copy some files over.These are just prototype devices, perhaps the released models will contain USB ports. Or have Microsoft changed their mind on this requirement?
