ASUS has a couple of new motherboards coming down the pipeline very soon that introduce new features including support for SATA 6G storage and USB 3.0 devices. Both SATA 6G and USB 3.0 technologies are awaiting actual devices that utilize them to hit the streets, but it is good to see ASUS taking the high ground and offering these options on motherboard for users that want future-proof their new builds.
The SATA 6G support is powered by the Marvell 9123 chipset and a high-speed PCIe bridge chip while the USB 3.0 is coming from an unknown add-on controller.
UPDATE: ASUS got back to me and told us that the USB 3.0 implementation on both of these motherboards uses the NEC UPD720200 chipset on a single PCIe 2.0 x1 lane that supports up to 5.0 Gb/s. Considering 4.8 Gb/s is the theoretical maximum speed for USB 3.0, this implementation should have all the bandwidth you could need.
