I think you'll be looking for the up comming CX board. It will not be a full size ATX board, but a mini-ATX. It will use the ArticaP, use DDR RAM, USB (2.0?). It will probably have 2 or 3 PCI slot and an AGP slot. Specifications are abit sketchy at the moment. I think Firewire was mentioned at one point. Not sure on the AGP slot specs. Also, I believe it will have Gigabit, too.
Basically, we know almost nothing about it. Stay tuned.
