It definitely looks like a nice player, as long as they didn't mess anything up. If the reviews are good, I may even replace my OPPO. I like all of the streaming options.
The upconversion of that Denon won't be able to compete with the Oppo bpd-83. Also, the Oppo has the blu-tv feature which looks like has the ability to add apps to stream many different things.
