970 Motherboard and Chip Delivery?

MacBidouille posts some details about prototype motherboards for the PowerPC 970. As reported before, they indicate that the motherboards are more rectangular than square and have 8 RAM connectors -- 4 of which were covered by a Do Not Use sticker. They speculate on the reasons why this might be the case, but have no definitive information.

Meanwhile, LoopRumors posts what they claim to be shipment information to Foxconn. They report that Foxconn has already received 20,000 1.4GHz 970s and 40,000 1.6GHz 970s. 40,000 1.8GHz 970s are reportly due tommorrow.
