This has probably been asked before, but I've been waiting for the 8805A before upgrading from my 8802A. Been looking over the HDMI 2.1 changes I don't think I would use any of the differences. My other reason for waiting was for the DTS Pro upgrade, so I could use the 13 speakers I now have and add 2 more for side heights. So my question is whether a present 8805 will still have the capability to update to DTS PRO when it's available? Could I upgrade to an 8805 now if I don't care about HDMI 2.1?
