I agree that Wifi and the memory card interface is not needed but HDMI is really quite important.
With analogue output only, the BD movies could be downres'ed when played.
It would seem foolish to spend so much on a console and be locked in to the past with the outputs.
Some people might not care... but many will or at least should care
Anyways... $600 for me too. I want the WiFi features for PSP interactivity as well
