I am also interested. I was using Rocket Games' NGUI Playmaker scripts. I made the switch to Playmaker's uGUI actions, but those actions are missing things like the Rocket Games action, NGUI Set Active (which only activates children under an NGUI game-object that are checked to be active, while simply using Activate Game Object for a uGUI object activates ALL the children, even the ones you don't want to activate). I could make the switch to uGUI, but if the Rocket Games asset (or something like it) was available for Unity 5, I probably wouldn't switch for now.
