Here is my translation of that Yu interview in the German magazine.
I didn't translate everything because some of the questions are just about Yu's hobbies etc.
I'm not a native english speaker, i tried my best.
Question 1 to Yu:
You said that Shenmue 3 will be bigger than you thought at first?
Yu's answer:
Yes, the game will probably be three times as big as i had in mind at the beginning. One of the villages has over 200 residents now instead of just 50. This village alone is five times bigger than i had in mind.
Question 2 to Yu:
But still - Shenmue 3 has not the same budget as 1 or 2. What do you have to change in the game because of that?
Yu's answer:
The story is still intact but i had to adjust some of the extra elements and details. We talked about the 200 people in that village - maybe we will even have 400 in the end, i didn't decide yet. You have to remember that all the city / village residents in 1 & 2 had a "real" simulated life, thats a really complicated and tough quest and the budget for Shenmue 3 is probably not big enough to do that again.
Question 3 to Yu:
Will there be voices and sound for everything in the game?
Yu's answer:
We don't know yet. To tell the truth - the amount of text is getting bigger and bigger and not all of it is planned, so we don't know if all of it will be available with sound.
Question 4 to Yu:
Will you use the voice actors from 1 & 2?
Yu's answer:
Ryo's english and japanese voice will be the same in Shenmue 3. I can't tell you anything about the other people yet.
Question 5 to Yu:
Shenmue 3 will be only available on PS4 and PC, why is that?
Yu's answer:
That's simple - it's just because of our partnership with Sony and their support at the E3 2015.
Question 6 to Yu:
Did you ever thought about how you could tell the story without a real Shenmue 3?
Yu's answer:
Yes, i thought about a mobile game before.
Question 7 to Yu:
There were a lot of critical responses for the Shenmue 3 teaser. What would you tell the people who feel dissappointed?
Yu's answer:
We don't have any facial expressions in the game right now and none of the character models are final yet. So it will look different and better in the final game. The teaser is not representing the quality of the final game, we are still in the middle of developing. And of course you have to remember the budget. The budget is good enough for our game, but its pretty small if you compare it to other games right now. We can't keep up with big modern games. We would need a way bigger budget (ten times bigger than now) to make perfect modern graphics. So we need to find a good middle way between good graphics and good content. Please don't expect highend graphics, Shenmue 3 is not about that.
