Most of xH6x chipsets have support for 12 to 14 USB 2.0 ports but not a single one has support for USB 3.0. There might be some vendors of Huron River notebooks who will be brave enough to implement third party USB 3.0 chips and get the USB3.0 support to notebooks.
The only good new for 6 series of chipsets is that all of them support SATA 6 Gb/s or SATA 3.0, and you will at least get faster hard drive protocol that might get your system to run a bit faster.
In this particular case, Intel is slowing down the adoption of much faster standard, simply as its much cheaper to develop a chipset with USB 2.0 and repackage it and sell it all over again.
It doesn’t look like that Intel will officially support USB 3.0 in its chipsets before it introduces its 2012 platforms.
