With all 8 of Dragon Ball FighterZ's currently announced DLC now released, you'd be forgiven for thinking DBFZ's roster has reached its conclusion. Bandai Namco and Arc System Works have made no announcements for a second FighterZ Pass, nor have there been any leaks or hints that one is on its way, so there's no concrete evidence that we'll actually get one, right?
At this point, it'd be kinda weird if we didn't get another DLC pack.
Fighting game fans will buy whatever DLC you throw their way, though Arc System Works using DLC slots for Base Goku and Base Vegeta was... less than stellar, shall we say.
So, if Bandai Namco release a Mr Popo DLC and made him top tier, you know Dragon Ball FighterZ's community is gonna buy him regardless, just to get that competitive edge. They don't call it a sport for nothing.
