Does not compute. Porting to Linux Desktop takes much more effort than porting to a console. With a console you have fixed hardware specs and you can tune everything in your software stack to fit your needs. With their current effort they have to worry about all the different hardware setups, future Ubuntu versions, integration into Unity (or whatever DE). All that is unneeded for a console.
And so far the console are just rumours and support for Desktop Linux is going Beta.
