I just want one a little more bulkier than the DS3 is. My main issue is that with the PS3 controller it always felt like it was "resting" in my hand while with the 360 controller I was actually 'holding' onto something.
And people asking for the sticks reversed ... I'm fairly certain it's just a preference, it's not "OH SHIT! I can't play gamez now!". I just like the 360 layout more, I still have owned PS1, PS2, PS3, and will own a PS4 regardless.
I really like the look of the new controller though, it seems like something I can 'grip' more-so than something I need to have 'rest' in my hands.
