Oh wow, just because things like automatic 3D monitor or screen are barely out for sell does not automatically means the Dev should decided to add in 3d feature into the game, not to mention I doubt people would go into the trouble in buying these screen in replacing the one they have now.
When you can actually "see into" the world, and have things "reach out" to your face, there is nothing like it...
There is no future without history and this is true when we look into Beth's history of developing a new game. One of the common trend is the debugging department. Daggerfall was basically beta, Morrowind crashes time and time again, Oblivion crashes just by walking around, and Fallout 3 was horrible with GFW.
I know that Direct3D would make possible for 3D but it is requirement of something in a caliber of having a device that require one to even use the feature.
