Question about patch 2.0

[Frozen Death Knight]

I doubt it. How does it look like? Skeleton king appears already spawned?

That's not even a cutscene, man. A cutscene is when you lose control of your character and watch a short film where characters interact and/or progress the story further. Like the part where the Skeleton King before the fight appears as a ghost and say "You will never defeat me!", for instance. You no longer have to manually skip those cutscenes by pressing a button if you just change the settings.
