Ahh, I can we are just going to have to agree to disagree on quite a few things. When I listen to someone speak, particularly for something like this, I listen to the message, not the words. There is much PR involved, and I'm just going to flat out say there is nothing that will sell me on the idea that Wii Fit Trainer was chosen because Sakurai saw her and thought of a character that could 'powerup' with her breath, as plenty of other people can do that. If anything, it was reverse engineered that he wanted to include her and it happened to fit.
I mean, the result is the result buddy. You can decide for it what you want, regardless of how you deem it. Obviously they never say they cut a character in favor of another, that would merely build resentment for a new character from the fan base of the old character. This makes no sense. You cut one, introduce the other, and pretend they have no ties. Would you feel better if I said just cut Jigglypuff, and also, completely unrelated, introduce a floating character who can do the things I said Boo would do?
Yes, which is why it is important not to speak by stating things like, "This is what regulates cuts." You do not know what regulates cuts. It would be different to state, "in the single past game we saw cuts, this is what we can observe." Yet to assert yourself as an authority immediately puts a reader away, because neither you or I have authority on what actually is the decision making process, only by trying to ascertain what that decision making process is.
