onlyclave - where are you hearing that Denon will not be releasing a 4313 model later this year? You are the first I have heard state (emphatically) that this will not happen. What is your source?
mj - careful with the new Onkyo line (809 -> 818) possibly just repackaging with a new name from last years models, and as eluded to in this thread, without significant changes (as done by all manufacturers/models). Unfortunately, after the X08/XX08 model fiasco, Onkyo was again forced to issue a press release recently with the X09 models due to shutting down.
I don't think economic lessons are necessary to explain the dearth of inovations anticipated this year... I just wish I had the economic power in my bank account to stimulate the economy with my pursuit of Audio/Video nervana!
