Future plans for character customisation?

So I was just curious really as to what the plans are concerning customisation of your avatar. I understand that there are plans to add female player models but is that as far as things are going to go?

Ideally, I would prefer to have the option to change other elements such as skin colour, hair and facial hair style and colour. Maybe a couple of varieties for facial features too. Other than that, I suppose the only other reasonable options would be clothing colours, perhaps using dyes or something.

It would just be handy of being able to identify other players from one another, aside from just looking at their names obviously.
