I hear people speculating that you had to beat something, but I've never seen SE say anything like that. I've also had discussions with legacy players who have not beaten it and say they get the new cut scenes. If there was a link from SE that said only people who have progressed so far in 1.0's story will get the special cut scenes and I missed it, then please link it so I can know.

In regards to it not being much: It may not seem like much right now, but we don't know what the rest of the story is. It could be some really cool stuff. It could be completely minor and be irrelevant. We don't really know.
