Hmmm...there is Blue-Ray (Japanese), HD-DVD (DVD Forum), EVD (Chinese) and FVD (Taiwan/Microsoft).
Think DVD-A/SACD format war was/is a drag?
I believe the 950 is gonna be a keeper for a long time to come. The 6 ch bypass is excellent, and will no doubt work with any of the above formats.
The 770, likewise, is a bargain that will remain in your rack for as long or longer.
The problem will be with the players and software titles, IMO. The 950/770 will do them all beautifully.
No way I see the 950/770 a sideways move from a Denon 3803.
Buy the combo, A/B it for yourself, and in any case, at least keep the 770.
As far as holding out for anything Dolby, much less their version of another crapola matrix scheme...sheesh.
