Well. Dead or Alive always was a series I could enjoy playing with friends, but for the life of me could never get good at or thoroughly invested in. (Though I did make it through that stupid 2-hour tutorial in 5 somehow. Not that it helped, just made me try to counter everything at the wrong height) Only a handful of characters appealed, and one of them already being the star of another series doesn't help. That said, I know a diehard friend who is going to get this and coerce me into getting it just to play with him, so I guess I'm down. Looks pretty at this point, I'll give it that.
So yeah, the whole fanservice thing is a hard split between getting on board or leaving the series for a number of people, and is really not needed to be focused on personally. You'll likely still get your sexy alt outfits like everyone else does and jiggle slider in the options menu, but it'll probably help them draw in newcomers at least to reel it in on the default stuff.
Also, you got a Samus situation with Kasumi, going from wearing less to more
Spoiler, click to toggle visibiltyand still find them making ways to make the full-body new outfit still appear like fanservice. So it's not a big deal anyways.
