Do we know if the motherboards that will support BD processors will provide 2x16 PCIe lanes for Crossfire or they will have 2x8 like the SB platform ?

Also anyone knows any rumors about how strong/fast will be the HDD support compared to ICH10 and P67 Express Chipset ? I guess they will provide native support for Sata x 6Gb/s and not only from some Marvell controller am i right? What about USB3 ?
