IMO, Netflix streaming isn't great period
So, I would probalby not use that as a factor in buying a
high def player.
I would honestly choose the Panasonics over the Sony anyway. You probably won't find many reviews of them yet, as they are pretty new.
As for 3D, the current players are mostly designed to support it, but it isn't available yet. AFAIK, there is only one 3D disc on the market right now anyway and it is $349 (starter kit, includes glasses)
