I remember we got a "devkit" into the studio before public release: it was an entire 1u server.
How are we supposed to use a 1u devkit!? Had no one on their team ever do console work!?
Console devkits fit on a desk because that is where a console devkit needs to go. On the porting engineer's desk, so they can do the work.
In the end Google announced the non-sense business model and we saw the writing on the wall. I do not think that devkit ever got setup.
