I honestly think it's only going to get better, and I do think they are listening to the community more than we think. There are likely always going to be some things that don't measure up or aren't quite what people wanted (Gen 7 having mostly only t-shirts and shorts and lacking varirty in types of clothing comes to mind. It fit the tropical region theme but was still a bit dissapointing for fans and was commented on a lot). Since X/Y though, they darkened the skin tones (which was a complaint in X/Y) made it so we could remove our hats (another thing fans were vocal about in gen 6), and added more hair colours. There were more hair cuts (even if guys still had much fewer then girls) and there were way more clothes, even if they lacked variety. The models were better then the chibi models in X/Y, and the girls and guys shared some outfits like the trial guide, team skull and Pikachu outfits (styled slightly different to fit the model, but having the same clothing options for girls and guys was another thing fans talked about a lot).
So, honestly, I expect it to only go up. I still think that girls will likely have more hair style options then guys, and that they won't make every outfit gender neutral and wearable by girl or guy, but I think we will see a few more hair style options, a few new hair colours, more clothes that match between girls and guys, and more clothing variety. I could see them doing a bit more facial customization, by this I just mean more make up for girls besides lipstick and some facial hair options for guys, mahbe even adding freckles as an option. Perhaps they will add a jewellery option, or maybe even a coat option or something. I don't expect it to jump up exponentially, but I think it will still be a jump in the right direction.
