lol love that tweet and very interested to see what comes of it!
To be honest though, we could play a game where I upload a random picture of any object in my house, and someone on here could probably find it within one of the Shenmue games
That's just the nature of the games, due to the sheer detail that they contain.
I still think that they are working with Yu on something, and that is what we will hear about in a few weeks. My guess is that he is being brought on as an advisor for their games, with the endgame being the aim of raising enough money to continue the Shenmue series. That kind of announcement would be awesome, as one, we would be getting more games from Yu (in some sense), two, he would be learning more about the state of the industry as it is currently (which would bring Shenmue 3 up to the quality and technical level that is expected today from "modern" gamers), and finally, three, we would be getting a confirmation that ultimately more Shenmue is coming in the future, instead of having this uneasy feeling where we do not know what's going to happen.
I hope that I'm wrong and we get a Shenmue specific announcement though, that would be the dream! If it was 110 Industries (and Yu's) long-term goal to help Yu make Shenmue IV, then maybe they could chuck some money towards helping Season 2 of Shenmue the Animation as that would fall inline with granting Shenmue IV a bigger audience, as people could watch Season 1 & 2, and jump right into S IV.
These next few weeks are going to be tough, that's for sure!
