You play RPGs vanilla? The first thing most people do is load mods, and aside from the odd UI mods, the most popular mods are always hair and head presets, and other character model improvements aimed at making characters look hotter, especially the women. And that's just the boring Nexus mod community.
Give modders enough time, and I'm sure they'll be fixing the dialogue too. With modern AI v2t modders can do just about anything they want with dialogue. I haven't kept up with my Skyrim mods lately (hard enough to run 800+ mods already) but I'm pretty sure they've had a few entirely new AI-driven companions that can speak and sound like actual voice actors. That'll be the standard with all RPGs sooner or later.
