Rereading the topic, I think we're all saying the same things, just with some different interpretations.
Vision changes over time. His vision of a VF RPG became the Shenmue we know and love, and 2000's vision for Shenmue III won't match 2015's, which won't match 2017's. That's fine, because the best visions grow and evolve. Artists grow, learn, and thrive, assimilating new ideas and information, discarding some and running with others. Yu should listen to the fans, but what he takes from them should ultimately be his call.
We all want Yu's vision to be realized. Basically, we're all saying is this: "We want him to follow his vision within certain parameters of what's expected from a Shenmue game." One side isn't saying that they truly want him complete freedom to deliver Shenmue in the form of a Skittles potato salad if that's what he wants, nor is the other saying he *should* if that's what the fans demand. If he wants Ryo with Joy and it's reasonable and integral to his vision, we agree that he should run with it even if we prefer Nozomi or Shenhua, but if he wants to make Shenmue III in the form of interpretive dance riffed from the audience by Crow and Servo, he should probably listen to the fans and stick to a video game set in Baisha village!
I have faith in Yu, and trust him to grow and evolve in a way that's true to himself and Shenmue!
(I had a big, rambly post here that was maybe more antagonistic than I intended. Sorry about that!)
