Just how old is the ATV2? Isn't it time for a refresh yet? I realize this isn't refreshed every year like everything else Apple, but 720p? Seriously? As an iPhone and iPad owner I really want the ATV for the obvious advantages compared to say the Rocku, but 720p is antiquated and I'd hate to go buy an ATV now and have them release the ATV3 early next year. Any thoughts on how much longer till Apple releases an ATV3?
