I'm guessing that Patrick probably still has pcb layout and parts list, but couldn't release them without permission from Sigmatel who, as far as I know, owns the intellectual rights to them.

Also, I'm certain that if another run were going to be made, they'd want to address some of the shortcomings, like 100mb or gigabit ethernet, USB 2.0 master, sata hard drives, more memory and faster processor, video output, etc..

You can see where it would quickly get prohibitively expensive. I'd be much more interested in Sigmatel open sourcing the player software so it could be ported to work on standard pc hardware.
