Japanese site Famitsu.com today published a new interview with Yu Suzuki, in commemoration of the release of the recent Powerdrift 3D on the Nintendo 3DS, centered mainly around various arcade games he worked on at his time with Sega.
The good news for Shenmue fans is that the interview contains mention of Shenmue 3 in a few places, including some direct comments by Yu Suzuki.
I've extracted and translated the relevant parts here:

My favorite part is where he states that his ideal graphical vision, going back to the early arcade days, has never changed - and he gives a Shenmue 3 image as an example of that ideal.
