Do want!
I'm a little late with my 2-cents, but ... yes, I've been hoping for hor+ instead of vert- for quite some time. I'm running the Matrox solution -- which is the "simplest" since it just tricks the video card into thinking there's a very wide, squat monitor attached. With the current vert- solution, the lost real estate far outweighs the subtle gains to peripheral vision. And having to zoom waaaaay out to see your feet means that the 'insta-zoom-in' when you put your back to a wall is intolerable. I thought I hated cave missions BEFORE!
Although, I'll fullscreen it for flying around Cimerora. Freakin' beautiful.
I work around it by playing in windowed mode, and shrinking in the edges until I have about, oh, 1/3 of a screen on either side monitor. Just enough for a map & a combat attributes window on either side. That's "enough" gameplay improvement for me to find the triple monitors worth it, but I'd love a real solution. I agree with the analogy about "VHS pan-n-scan". Sometimes, you just have to keep up.
I got all 'cited inside when I heard about "upgraded video" for I-17. But .. alas. So I can only keep my fingers crossed for Going Rogue.
