If i remember well, Replicell and Shisheido didnt broke up in good terms, there were even threats of legal action from Shiseido part. Maybe the perceived lack of optimism from CEO Lee Bucker is simply the fact that he simply doesnt know, as Shiseido doenst communicate with him after the relations cut, or even that he holds some kind of grudge against the japanese, even thought it would benefit his company to have it launched in japan.
Just a educated guess.
