My 805 recently needed an update and to put it simply was a major pain in the a**.
When you say needed, what exactly did you gain? What version of FW did you previously have? I'm on 1.06, and I've not once considered bothering to upgrade.
I agree with everyone else here in that spending 1k to simply get internet update ability is a pretty ridiculous misallocation of money. My bluray player doesn't update over internet either, but that's not a reason for me to go buy a brand new one. OTOH, the 906 has some video features, dual hdmi outs, aud dyn vol/eq, etc, etc. Even with that all combined, do you really need that stuff? If for video processing, I would venture to guess that you will get much better stuff with a stand alone with that money. If you have successfully implemented 1.08, do not expect another FW. Because the X06 models are out already, as you know.
Your Denon choices are lateral moves. Except for the internet thing perhaps.
1k can get you many other additions that will have much more meaningful impact. Room treatments, sub upgrades, speaker upgrades, HT seating, video processor, you name it. JMO.
