Working in Quality Assurance myself I can say that QA is often overlooked by most industries not just the gaming and often its cut out altogether due to pressures of sales and marketing departments applying stress tactics.
For the past few years now I have been employed by a company who focuses in on intrusion detection and response systems for all types of transportation departments (air, water, road and rail) even holding military contracts for some countries in the middle east. With that said we have a whopping two man crew to do total system and integrations testing on a system that makes Oblivion pale by comparison in complexity.
Personally speaking the only way a company now a days can release rock solid software is to control all aspects of hardware. Secondly you need management who actually knows how QA works with competent QA staff to create and actaully execute real test cases and lastly the marketing and sales pigs need to be hog tied!
