Quoting another user who apparently inquired with AJ about the delay, the response they received was evidently, "As for the Paypal, Mr. Suzuki did mention it on the Twitch broadcast. There are reasons yes, none of which I am personally privy to. But you can imagine our situation is slightly more complicated than your average Kickstarter."
For whatever it's worth. I for one, being a) someone who's played Shenmue, b) someone who's waited 14 years for this, and c) have had to withstand accusations of being a paid astroturfer for weeks everywhere I went to defend and promote the Kickstarter, am choosing to be patient. Since you know. That's sort of what we do lol.
