That is awesome! I've always preferred the style of DualShock controllers to that of Xbox controllers so I'm glad that Steam will natively support this now. I only hope the UI will reflect the changes as well and show the correct symbols for controls; ie; Triangle, Circle, Square and X.
EDIT: It looks like the UI in Big Picture mode will show the correct PS icons. Games however will still show ABXY icons which will correspond to a mapping on the DS4.
I think it will be interesting to see if any game devs update their games to show the correct icons once this update lands.
