Which of the announced changes/enhancements for DS4 have you most excited?

Personally I have to say it's the seemingly improved aesthetics.  In fact I've been annoyed holding DS3 ever since I saw it.  It looks like it has rubberized grips on the bottom or at least is more contoured so that's cool.  The sticks and triggers are of course a big improvement as well.

hmm has to be between the Share button or the new D-Pad

Favorite: Headphone jack

Least favorite: Touch Pad

Share... no doubt.

Isn't the D-Pad somewhat the same?

Share.

I love bragging and showing off my skillz (or lack of in certain game genres, like shooters, which can make my friends go rofl).

All of it except for the touchpad. Just because I don't know what it will be used for just yet.

Aesthetically it looks pretty slick. Share button is a really cool idea. I'm pretty happy for the headphone jack myself.

Double analogs! Hellz yeah, this is going to be 'uge!!

see it goes beyond that for me.  There are so many moments over the years that I've told my friends about, but I would have loved to have been able to show them.  That's why it's genius that it continuously records so you don't have to say "I'll capture this segment" you can just play and when something awesome or funny happens you can preserve it forever.  I remember I beat my one friend in NHL 2011 by scoring 2 times in the final 10 seconds to win 2-1.  Hardly anyone believes it unless I have him there to confirm (which he does cause he's a good sport).  It's moments like those I'd love to have.  Or even great SP moments like when I almost didn't get the GoW2 plat because I was stuck on challenge 2 (kill 10 enemies in the air before time's up) and I got it with ZERO seconds showing on the clock!  If it records dialog from any headset you're wearing that would be awesome because I always say frantic things to compliment moments like those but I just love this feature either way.  

The light.
