I doubt that it's Shenmue 3. Hopefully it has to do with HD remasters.
On a side note, I think that Shenmue 3 would be super awesome on the Xbox One. While I am not much of a Kinect fan, I think that Shenmue 3 could actually integrate it quite nicely. For example, wouldn't it be cool to have Kinect events instead of QuickTime events. Like doing karate moves and such for special scenes. Theres also the odd jobs that would also be more enjoyable with Kinect interactivity.
