Back when I was doing some work for Adventurer's Vault I got a copy of the D&D 4E style guide. I thought some of the ideas for the new dwarves were interesting, so when it came time for my group to try 4E my character was a female dwarf fighter, who I sketched during a couple of sessions:
Some time later I was talking with William O'Connor (Website Blog Dracopedia) who had done a lot of concept work for 4E. He told me they had made a concerted effort to make female dwarves interesting to players -- research had shown they were played even less than monster races.
So I guess their new marketing targeted me. I'm always surprised when that happens.
