I'm not very interested in it, but an important thing to remember is that this is not being made by Bethesda Game Studios, the guys who work on the TES series. It's a different studio entirely, under the publishing arm of Bethesda Softworks, so this should have no impact whatsoever on the team working on Skyrim and future single player TES titles.
I really hope this is the case, but we know what happened to Wacraft. WoW was released 7 years ago, and the main series hasn't seen a sequel yet. Why make two similar products that will compete with player's money? Why pull players away from TES:Online with TES:VI? Hopefully, Zenimax won't be
that brutal with their business plans.
