I see the current emuster system as being more grounded in reality. Live drills always were a waste. If there ever is a real emergency many/most people will forget everything they saw in either the video or a live demonstration (although I'm trying to think of anything that's actually useful), especially if there was something obviously bad going on. All they really need to know is where their muster station is, and I'm sure a bunch will forget that. I'm sure the crew knows this and is ready for it. For that matter, there will be at least some time to give the standard demo while people wait to board lifeboats and I would expect that they do.
Just out curiosity, does anyone know what crew training tells them to expect? And, how are things supposed to go beyond the part that passengers currently see.
