Remember Yugi vs Kaiba in Battle City? We got so much stuff going on then just the duel. Hey, Blue Angel's in a coma right now just like Joey was for that duel. Maybe she'll have her own dream/coma tournament just like Joey did.
Yugi vs Kaiba had alot of build up and was a major event, so it getting six episodes made sense, but Yusaku vs Revolver seems less anticipated by comparison. And as much as I like Aoi, I hope she stays out of the way during the duel cuz Joey-like coma shenanigans from her would be a waste of time from my perspective. ^^;
