Bethesda is just the publisher... Which, might mean you should be more worried. Because I cannot think of a single game that Bethesda just published that didn't have serious issues. The most high profile of recent is Rage, which seemed very much to be a love or hate affair. Less recently, Brink and Hunted: the Demon's Forge.
So... Yeah. Not a real history of quality there.
The game looks great but you are sadly right about Bethesda when it comes to games not called Fallout or Elder Scrolls.
