That was their messaging, not mine, and I understand the skepticism given the results of the DoA tournament scene (it's never been great).There is no difference with breast sizes in DoA6, and the only scaling back on the jiggle was getting rid of the over-the-top OMG setting which was an unlockable bonus in the previous game. DoA6 is a weird, budget non-expansion rather than a proper sequel to DoA5, recycling a great deal of base game and DLC content from 5:LR all while still managing to often have poorer character models and environments/effects. They claimed to want to make something that would be more appropriate for eSports, but the marketing was a constant series of contradictions (from what was offered for the physical purchases in Japan to the "core values" streaming incident at Evo Japan), and DoA6 has no more of a tournament presence in the FGC than previous games, including failing to make Evo like Team Ninja wanted it to while SCVI did. No one familiar with what happened the last time they tried to tone down DoA only to backpedal on it with the original DoA5 ever took them seriously.
That said, I would say that I don't see much difference between SFV and SCVI in respect to fanservice when compared to something like DoA5:LR. It was mainly tournaments aired on ESPN where there were more restrictions imposed on what outfits were considered acceptable (default Laura presented the least issues while still not being something that broadcasters would be happy with, Cammy and R. Mika being more of a problem in that regard). I'm not really under the impression that they took that into consideration when taking Poison's default into account.
Poison's new default actually does show less skin, cleavage, and cheek than SFIV (though not by much...), but I also think there's a big difference between a character like Poison who (like Ivy in Soul Calibur) makes overt attempts to appear sexy and sexual (it's literally a part of her character), unlike characters in Soul Calibur like, say, Talim or Hilde.
Because you know what Talim certainly didn't need? A thong and underboob. And yet that's her default look. Hilde never needed big boob armor. Cassandra didn't need to lose her undershirt. Seong Mi-na's skirt is barely held on at this point. Etc.
Not every character needs to be IVY. And yet every character has shed clothing like Ivy in SCVI. It's especially egregious compared to the men.
