They haven't really used a propietary format with their consoles since the N64.
The GameCube and Wii both use DVD, they just made a few modifications to it.
Just like the XBox 1 ... technically the sytem out of the box did not play DVD Video either, you had to buy the remote control + dongle to open the DVD playback. That was the same thing Nintendo was going to do with the Wii but by 2006 it became pointless to offer it.
It's quite possible the next machine will be the same type of deal just with Blu-Ray. This time they might actually release the dongle accessorie though.
