I'll say this: I wasn't wrong, but there was a huge shift in the project from when I heard about it and the final form. It had a lot to do with a change in the director of the DLC, as the original director left a third of the way in the project to join Nintendo. But I'll talk more about that at another time.
People can choose to believe or not of course, but this is from different people and discussions anyways. I can only share what I hear from others and if they don't mind me sharing as I don't work in these companies but I know quite a few people. One person didn't want me to share, one didn't care, so I was conflicted in mentioning. In this case I think it may be true due to the two very different people I heard it from basically saying the same thing, but honestly it's kind of very broad anyway so I don't know how much it's worth. I probably shouldn't say, but I kind of figure a lot of people might already know this if two different people could tell me.
And frankly it in itself leaves a lot to speculation. For the record I haven't seen this in any way, shape, or form, I'm just passing what I've heard.
