I think they'll be the same. Honoka's rack will probably still be massive if not more weight than majority of the cast but this time maybe they'll show her fighting powers besides zooming on her tits to get people to play the game.
Why would they be redesigned? They're popular and well-known almost solely for their appearance. Changing them looks-wise makes no sense. I would like them to change Honoka's fighting style though; I hate the whole Edge Master thing outside of Soul Calibur.
They probably will give them more combat oriented gear like Marie Rose I can see her still wearing her dress but Honoka will probably get something more street xD And yeah as long as Honokas boobs aren't focused on she should be fine, I mean look at Josie Rizal in Tekken xD
I don't think that would be a problem as long as TN keeps them covered but tbh thats how its gonna be xD ger default outfits don't show cleavage and it seems just her boob presence is what makes her design tbh xD
