Somehow though, I think the people doing the PC98 English patches already had a translated script for the endings.
For that matter, seeing as how neither the author, nor anyone on Something Awful has mentioned this rule of sorts that ZUN had put forth, it makes me think that the LPer will continue showing the endings even in the windows games. And on that note, do you believe that the videos will have the endings edited out once the English patches are released? This being a Something Awful LP, a lot of people are going to see them, many who haven't earned the right, and many more who haven't even played the game at all. This is precisely the sort of scenario ZUN feared when he made that rule.
Not that I'm not grateful to finally see what was going on in the endings, but I'm simply concerned over how casually the endings are being shown, as if it were just a matter of course.
