Street Fighter 2 WW Arcade Questions

Found this kit manual online. And a few things stood out about it. One the logo is different and it’s copyrighted 1990??? Any reason why this would have a 1990 copyright date and a different logo? A beta version? Or just a fake/modified one?

That’s when it was supposed to be released as opposed to 1991…

Ok I see. Was there any reason for the delay?
