Is the default DUrge gonna be a Shadow Sorcerer, now?

This gif from the Patch 8 announcement makes me wonder if they'll change the default white dragonborn Dark Urge from a Storm Sorcerer to a Shadow Sorcerer.

I mean, it makes sense. It keeps him as his original class (Sorcerer) but changes him to a subclass that makes sense. Besides, the sorcerer in this clip is very clearly the default DUrge.
