This rumor is as persistent and false as the old "Dragon Ball was supposed to end at the Freeza Arc" and "Nakama is a magical word that means 'a Bond deeper than family' and is thus untranslatable".
The Buggy and Coby-meppo cover stories were rated just as highly as any other episode during those eras. There's no reason to believe low-ratings, or fear of low-ratings, are stopping those episodes.
You just named like… most of them...
I'm most interesting in Meet Baroque Works and Enel's.
I see. I guess I was also faked by the rumor. Then I do wonder why they never tried to animate the other covers up until now.
Yeah, I guess I shouldn't beat around the bush and say I just wanna see all of them, lol.
