The title should be updated since Sony is not actually part of this Kickstarter, they simply provided the creator with a platform to promote his project because they are fans of his work.

That isn't to say that they aren't potentially part of the follow-on funding deals though (which we know nothing about), since everyone is pretty sure that this Kickstarter is a "proof of interest" gate for further funding. You could never make Shenmue 3 with only $2 million dollars.
