Hrothgar are among the least played race/gender combinations present in the game at the moment. I don't see that changing drastically anytime soon. Especially since many of those pushing for them to be added do so not because they want to play one themselves but because they've convinced themselves that it'd be 'interesting' to see them as a playable race. Even Yoshi-P is guilty of that. He really wanted to see a beast race made playable, yet he plays a female lalafell.

I'd sooner see enhanced character customisation for the playable races we have already, but if they do add another in the future...then hopefully it'll be something conventionally attractive as to be worth the extra work it'll take to make emotes, mounts and glamour fit.
