Every online and brick&morter store has them sold out or backordered, and I have learned that this has been the case for some weeks now. There are also rumors that the 5500 are discontinued. What's the story here? Even logitech's online store doesn't have any in stock. I was hoping to have ordered these this weekend, but I am growing impatient and if Logitech does clarify the situation here soon, I'll just end up going with the Klipsch Promedia Ultra.
