All I can hope for now is that the modding community picks up the slack since SE is incapable of actually putting any effort when it comes to texture work. Of course this is never going to be sanctioned by SE, so it will most likely be another parser situation, so if client side modifications do become possible, it's going to be a 'don't ask, don't tell' situation. Other than that all we can do is give it time, someone somewhere is working on making it possible.
