better question, Wii U has a built in HDD?
i just assume they're going the Sony route with it and doing any 2.5" can work.
but yeah, they took the PC model of digital distribution which is smart. the net result for this will be sony and microsoft will be forced to loosen their deathgrip for their next systems too.
