I don't see what's to hate about the new controller. The shoulder buttons are improved, you've got some concave analog sticks, there's still a physical pause button, it weighs nearly the same, the feel will be about the same when you hold it, there's rubber grips on it, a built-in mic and speaker, and a headphone jack. What part of that is a step down from the old controller? If people don't like the look, I don't get it. I tend to look at the TV when I'm playing games. If the performance of the controller has improved, then truly that should be the thing that matters more.
@Doc-B: The sign in with Facebook type thing is a possible downside for me, too. However, I'd need to rewatch that part of the presentation. I know the guy mentioned that you'd still be able to use your user ID and avatar, but I don't remember to what extent you could use those. Hopefully there's some way to just opt out of using your real details. I do hate the internet's recent push to get everyone to stop being anonymous. I wonder if you could just put “Seibei4211” in the name and put an avatar as your picture though. Anyway, if Sony's thinking about doing this, I'm guessing Microsoft might be as well.
