In my anticipation of the update in Germany I've been reading up on some old posts from 2004 and such about the 3rd installment.
So I was thinking in the lead up to Gamescom we could comb through some old theories about Shenmue III over the many years that have been proven or disproven based on what we know. I'll start I remember one being Lan Di will appear at the start of 3 in the cave and take Shenhua or the mirror. It's still technically possible but with the game most likely starting from her house I don't think it will.
