It would be interesting to see the modern "handmade" movement (Casey Muratori of handmade hero fame) join the project. It would be so cool if it could, for example, replace Ubuntu as the basis for Steam OS. Seems like it's the perfect fit for something that requires high performance and low latency.
Unless this can run Linux binaries native, that sounds like a TON of work that would result in further fragmenting the Steam ecosystem. At the moment having the Steam console run Linux means they also support the entire Linux user base (which while admittedly small, is still likely large enough to help fund the console development work). There's no way the console sales can standalone justify the development work if it were running something as obscure as Haiku.
