Rambus does have some great lawyers, but the US Judicial system is having issues dealing with MS's lawyers, much less a little gnat like Rambus biting their asses.
I think it would be hilarious if Rambus tried to get DDR out of the XBox, Microsoft would mangle Rambus so hard it's not even funny...
I can see it now....5 way hostile take over, Intel, MS, Micron, Infineon and which is the 3rd major memory manufacturer trying to take down rambus? Maybe even nVidia...though Via seems to be allowed to produce non-Rambus chipset for intel chips so I don't see why nVidia wouldn't be.
