Bethesda, like many other PC game developers, have simply forgotten that the PC is what made them who they are today. Rather they are consumed by greed with how many more copies they can sell on the crapbox 360 and now neglect any PC development on their games other than making sure that the console ported game will run on the PC.
TES VI will probably be console exclusive looking at how severely neglected Skyrim was on the PC.
