11. Is there a plan for USB 3.0 or a faster USB 2.1?
No, but you've probably heard about the news already. Wired USB has come to an end with the introduction of the Certified Wireless USB 1.0 approved in May 2005. Everything will start to go wireless when wireless USB hub & USB dongles begin appearing in Q2 2006. The migration, ironically, could be jumpstarted by FreeScale's competing Cable-Free USB whose supporters promise to ship their wireless products much sooner than Certified Wireless USB counterparts.
