Interesting if they do indeed go with Xsens, they seem industry standard- which is incredibly exciting knowing it'll feature heavily in the battle system with current gen animation blending techniques.
Face capture like Giorgio suggested is an interesting one though. There are probably compelling cases for and against doing this, in the case of Shenmue III. The expense of doing it for both language tracks might be too much even if limited only to the core cast, but at the same time, it's probably less time consuming that manually syncing mouth movements to voice, so-
I can't believe they screwed the pooch with the picture resolution again though. Just host it somewhere other than Kickstarter. The update itself also has a few errors, and I'm not sure this is a Japanese to English issue either. More than likely whoever wrote the update isn't proof-reading.
