If anyone is interested, I just received an email from H/K Customer Support stating the 320 and 520 are shipping to dealers right now. I also asked when the website will be updated with info on the new units. Here is what I received: "The Avr320 and 520 receivers are shipping out to dealers as we speak. They should be arriving at dealers in large numbers over the next few weeks. The new website will be going live very shortly also."
