Game consoles and Linux

It's been announced long ago that PS3 will have Linux, though it's yet not sure if it's the actual OS for games or a dual-booting feature. Now there are people deciphering that an interview further emphasizes the possibility of Linux in Wii, too. And whether that is true or not, and whether Nintendo's Linux is a fully open platform or a proprietary one (except for code required to be published, eg. kernel), a fully open GNU/Linux for Wii is under development and scheduled to have something real available before Wii even ships.

With all this going on in entertainment devices and other embedded devices, one can only speculate if the possible successor for Xbox 360 will have Linux, too? Or would it be perhaps too humiliating to some parties...
