They definitely should work on expanding the CC options after they add male Viera and female Hrothgar.

While it'd be nice if they're considering body shape customization like yoshi-p mentioned, I think they should start with something simpler like adding more face options.
This should require less work since they don't need to refit gears.

Regarding the last races comment... well Yoshi-p said many things in the past that he ended up backtracking, like BLU for example.
