Don't get your hopes up... I very much doubt anything of significance will happen or be shared.
Finally confirming and promoting Shenmue III for the Chinese market is a big deal IMO, because it exposes the game to an enormous audience that could help secure the future of the series. If that's the good news Yu has to share, it's important, even if it is already a given considering the subtitling support.
In terms of new media I mostly agree, but Shenmue III's marketing has proven unpredictable in the past, and edging closer to release I don't think we can truly take anything for granted.
I like to keep an eye on the Shenmue III SteamDB page, which has been active in the last 24 hours. Valve can do periodical changes to their back-end that affect the update history on SteamDB (as a large batch of games under the same changenumber), but if I'm understanding correctly, if the changenumber only contains the game you're tracking it means the app is being updated on the developer side.
The application has been updated three times within a space of a day. This is still not hugely out of the ordinary for a game in development (REmake 2, which ships in January, has updated builds every few hours), but if it continues it might be a sign the PC build is getting a lot of attention, possibly to make it stable enough to show in the near future, or just because Ys Net are doing a sprint on that version of the game.
SteamDB won't be a clear indicator of what's really going on behind the scenes, so none of us should get
too invested in it, but if the next two weeks reveal a pattern... well you never know. I'm more optimistic about MAGIC next year than this, but I wouldn't write it off yet either.
