He said they will get their counterpart, but he didn't say anything about when. The alternative would have been announcing male Viera and not saying they were working on Hrothgar too, or holding back both character designs until they were ready together.

We normally get new races (ie. two new character models) every second expansion, so a 7.0 release would put Hrothgar right on schedule. We just got one in 6.0 and one in 7.0 instead of both together.
