If you're tired of 3D, you're tired of life.
I very much hope the developers support stereoscopic 3D with this game.
The difference between 2D and 3D is like looking at a moving picture, and being there. Stereoscopic 3D is incomparably more immersive than 2D.
For other players: If you've never experienced it, you are truly missing out (certain gamers' grumbles notwithstanding). It's like gaming in color for the first time. I played games, once, on a black and white television (a mere 15-20 years ago). I moved to colour, and I'd never go back. Likewise, playing in 2D seems lacking equally lacking--I'm not exaggerating. There is also a side-benefit for gameplay: you can effectively see more detail on a 1080p monitor with 3D enabled (since two different eyes are seeing two different sets of pixels). Additionally, on a nearly unconscious level, you are more able to gauge distances, especially in close-quarters combat (I've found that for slow-moving projectile weapons, I have far better aim when playing in 3D, because I can lead the crosshairs better).
For the developers: please allow gamers to run true 3D. The lack of true 3D support makes a joke of any game's efforts to be cutting-edge. I would go so far as to say that such an oversight breaks the game. I literally do not purcahse any 3D game without 3D Vision support (excluding this one, since it's an alpha). For me, lack of true 3D is so obvious it hurts.
