It's a surprise to no one that Square is disappointed in sales numbers. As the article says near the end they are infamous for being disappointed with not meeting very unrealistic targets. I don't own a PS5 to play it on, they haven't been in stock locally consistently. But from everything I've seen about the game, it's a middling to good game. So middling to good sales numbers should make them happy. And from what I can tell the numbers say that it's selling better than that.
