And now we have the closest thing to a statement we're going to get from Yoshi

First off, IMHO, extremely disrespectful. He literally laughed at the question, for merely saying that people have concerns. But to his quote:

In short, it was a lot of non answer and our feedback until 5.0 drops is irrelevant to him and his team.
