I think you should think about this objectively, especially considering that Logitech is now going to formulate a response that covers them in the best light.
Just because that is all they have stocked does not mean they aren't clearing inventory. They could have boxes and boxes of new versions of UE900s just sitting in a warehouse waiting for the old parts to clear the channel for all we know. Or they could just be ironing out issues with the new version. Who knows? I just don't understand why they didn't wait! I mean they already have the photos of the new version on their website and the packaging!
What Logitech does not want now is people leaving Amazon reviews which will make clearing the old stock impossible - because who on earth would buy an old version of something if the new version (which costs the same) is just around the corner?

From that perspective, it will be very interesting to see Logitech's response.
