I have a theory, but I suspect more glam may be genderlocked from here on out. As happy as people are for getting male Viera and female Hrothgar, I think it'll come at a cost. It'll be more sensible and less time consuming to give glam to specific body types, than for the team to overwork themselves in expanding it to ALL body types. So yes, people got want they wanted: more gender and races...

...for a price.
