So I'm considering getting the new Apple TV when it becomes available. I'm just wondering how much faster and responsive it will be compared to the previous generation. I've used streaming service like Netflix on a PS3 and stand alone Blu-ray player (currently) and they fairly sluggish overall. Netflix takes up to 2 minutes or more at times to buffer up to 1080p. Often it has to re-buffer so it's not consistent. Also will I need iTunes 12 to be able to use the new Apple TV??
