My inclining is that FURY [ Judging by the graphics show in the trailers] contain less information that needs to be transmitted to and from both the servers and the console than HD does.

So either SL has confirmed by their own actions that HD just eventually [with updates] overloaded the capabilities of the PSN.

or they are "Sorting it" so to speak, by using these graphics which would seem rather less finely delineated than HD's,saving bandwidth in the process,and not officially recognizing that things went horribly wrong with the 1.30-1.40 updates.
