Heise found a recent presentation that provides details about the Panther Point chipset series as well as its USB 3.0 integration. The presentation is apparently targeted at mainboard manufactureres as it is positioned as an effective appetizer to advertise the benefits of 5 Gbps USB 3.0 versus the current 480 Kbps USB 2.0.
According to Intel, Ivy Bridge and Panther Point boards should integrate four USB 3.0 ports. The technology will support Windows 7 and Windows 8, whiel Windows XP systems will run USB 3.0 ports as USB 2.0 interfaces via a native Windows EHCI driver.
There is no information when Intel's USB 3.0 integration will be available, but Heise speculates that Panther Point could be announced as series 7 chipsets at CES 2012.
