Not to stray off-topic but do you think (or did MS mention) they will give 1680x1050 as an option this year for Pc monitor users when they do their little 360 update this year? It would at least be in the middle kind of.
1680x1050 is a 16:10 resolution. I really doubt we'll ever see it - none of the competition seems to be planning on supporting it, either. Microsoft has certainly not made any mention of such a resolution. You could _possibly_ see something more like 1680x945 (which is 16:9), but like I said, I wouldn't bet the bank on it. The vast majority of folks will be playing their 360s on TVs, not computer monitors.
Back on topic: always set your 360 to output at your TV's native resolution. The 360 scales very nicely, and, more to the point, this will ensure that your TV's scaler doesn't introduce AV lag/desynchronization.
Will the 1080p upgrade look better? Probably not very much, considering the TV would be 37" (smallish for the resolution) and the source material would still just be 720p to 1080p for the most part.
