Why remove the trailer scenes?

Spoiler below!

There is a pig encounter in the cage area. Not the "scene pig" but an actual encounter. You get the encounter depending on how you play after having been there the first time.

Same with the other storage section making you go see the kids running through the hall...

Anybody here who played it a second time and got this encounter? I am on my second playthrough and now I have passed this part. No encounter. I'm curious what you have to do to get the sighting. I hope jens meant the cage part in the level with the centrifuge.

I saw the 3 parts of the centrifuge and thought I was missing one. I was turned around in this section because the levels change

When you go to the cold storage you approach from the right, when you leave this hallway is no longer there and you are required to go to the left (the Hallway physically changes) so you can do the stupid scripted chase scene.

So I went back through the "holding cells" section looking for a third canister. I did hear a monster spawn... after I was in the hallway leaving the holding cells... I didn't bother turning around to go find it so I didn't even see it in the said encounter.
