Hold the phone. I've been discussing this with a friend of mine who is much more in tune with gaming and computers then I, and he had this to say(this is a summary in my words):
"It depends on the developers of the game. If the game is intended for console use, it would likely by in 16:9. However, 16:10 is actually a more comon PC LCD ratio. If the game wasn't planned for console, it would be better for the developer to make it using 16:10." (this is an opinion, however)
Also, alot of "fullscreen" LCDs for computer use 5:4, not 4:3. Seems PC's use different resolutions then the Home theater world. Widescreen LCD and Fullscreen are not quite the same.
He summed up his points by saying this.
"it wouldn't really factor into my buying descision if i were to get a widescreen monitor... which means that i would go for a 20" 16:10 any day of the week over a 16:9 19" "
