Update: Nirvana328 lets us know that Logitech's cleared this one up in its forums, saying:
These boxes are just the regular boxes you have now and DO NOT have the 3.1 android update on them.
These boxes are not suppose to be released onto store floors until the update is officially released for everyone.
If a store is selling these boxes (it is just an added sticker on the box. Nothing else is different) they have released these boxes prematurely.
Original: We've seen leaks of Honeycomb for the Logitech Revue, and heard rumors of an inevitable OTA update that will bring the Android Market, but this one takes the cake. An unnamed big-box retailer has received a shipment of Revues with word on the package that they are updated, according to Engadget. We don't have much else here, the tipster wasn't able to verify that the units inside actually were running Android 3.1, but that's a pretty bold statement to make if it's just waiting for the OTA like the rest of us. Anybody out there prowling around their local electronics retailer? Might be a nice way to spend $99 and snatch up some new and improved Googley goodness.
