Have they shown ANY use whatsoever of that touchpad on the DS4? Is this going to be another Sixaxis, altho this time the useless feature takes up physical space on the controller?
Guerrilla said you can control the combat drone with the touchpad.
Blizzard said they want to use it for D3 inventory management.
Sucker Punch wants to use it for some kind of "finger scanning" minigame, but that sounded very gimmicky.
Other than that I haven't heard of anything, but I can imagine it will be great for UI navigation/browsing the web and stuff like that.
