Dragon Ball FighterZ's new fighters Vegito Blue and Fused Zamasu should be joining the roster by the end of May 2018 according to the Japanese V-Jump magazine. This magazine has served as a heads-up for game's future updates before as well.
Previously announced Fused Zamasu and the leaked Vegito Blue should be popping up in the game before 31 May 2018. These fighters are a part of DLC Pack 2, which could've easily been called DLC Pack Fusion due to both fighters being fused forms of other characters from Dragon Ball universe.
Vegito is pretty straightforward - he is probably the most powerful fighter to appear in Dragon Ball, pretty much battering any opponents he came across. He comes to exist when Vegeta and Goku fuse by using Potara earrings. Goku and Vegeta's fusion aversion was used as a plot device not to bring in Vegito when Jiren was pummeling both of them during the Tournament of Power in Dragon Ball Super, so we may never know what the fight between them would have looked like.
Fused Zamasu is the fusion of Goku Black and Zamasu, so he's technically a fusion of three characters - Goku, Zamasu and Future Zamasu. Or maybe it's two and a half? Anyway, he makes an appearance once Zamasu possesses Goku and then merges with another Zamasu from a different timeline.
There are no details on the DLC pack at the moment, but it is safe to assume they will have the same format as previous DLC characters Bardock and Broly, with each fighter costing £3,99, $4,99 or €4,99. These will, of course, be automatically added to the roster of Season Pass owners.

It may be worth noting that Dragon Ball FighterZ keeps shedding players on PC, with a peak of 2.608 players in the last 30 days, which translates to a staggering loss of 94,2 per cent of player base. When the game launched, it peaked at 44.234 players but now it's almost a ghost town on PC, so if potential newcomers are wondering whether to go for a PC or a console copy, that's where your answer may lie.
