Glitches and bugs require hundreds of testers to get anything done. And since Bethesda is one of the more secretive companies they can't do that without eventually leaking information. Most companies require the game to be launched for them to find the bugs and even then, most bugs need very specific circumstances. If you want bug-free games, play a linear RPG or shooter. Massive open world rpg's with different paths will create problems and will never be bug free unless it's really shallow.
