Roku’s been updating their website this week… and just accidentally spilled the beans on the Roku 3, given this new support site. We presume the new model is the same 4200x Engadget turned up via the FCC a few weeks back. Of course, beyond a name and model number, we’re most interested in new functionality. And perhaps the Roku 3 sports the beefier processing power required to run YouTube and overdue UI refresh. Further, we may be looking at a Broadcom chip that will also power Miracast. Regardless, we can’t imagine the wait will be long now… given the support rep volunteered March 6th availability.

UPDATE: We’ve got new intel, posted here – covering both Roku 3 hardware and software enhancements.

UPDATE 2: The Roku 3 is now here!
