Amazon and Best Buy are both offering the Apple TV for $89.99, $10 lower than Apple’s standard retail price, which suggests that the Cupertino-based company could be brewing up a refresh for the popular home entertainment box. In addition, Amazon has added a “2010” label next to the gadget, indicating that a 2011 model is on the way (or that it is simply distinguishing it from the earlier version). In May, a rumor surfaced that suggested Apple was building a new Apple TV that will support full 1080p video output, iCloud, 16GB of storage and a new A5 processor. It is unclear when Apple might unveil the new unit, but it would certainly make sense for it to hit store shelves in time for the holidays. In any case, this rumor should not be confused with other speculation that Apple is hard at work developing a Siri-enabled television set.
