Mitsuyoshi loves Shenmue, I have actually talked to him online about this, so unless he was lying to me for some random reason, he likes it!
SEGA has all the right in the world to hate the series, it was a big reason for them almost dying years back. The fact they are doing anything at ALL with the IP makes me happy. As long as I can play it and eventually find out what happens at the end of the story, I do not care what it is. I would even take like a series of books or even a crumpled up sheet of paper that sums up what happens in the rest of the story. Seriously.
