CD Projekt isn't competition, neither is Warhorse. You don't get amazing visuals from Bethesda, because their immersion factor is off the charts. No one, not even CD Projekt was making games like Morrowind, Oblivion or Fallout on the dated hardware that Bethesda was.
I fully expect the game to have very few loading screens, and tons more interactivity, this go round. They've spoke about it before as their next step.
In terms of detail and immersion, only Rockstar is in the same league as Bethesda, hence why both developers, get all the time and money, in the world to make whatever the hell they want. Witcher 3 is an excellent game, I enjoy it, but it doesn't come close to anything Bethesda has created.
