The jury is just now coming in and the 30D in low light beats the 40D; at high ISO's the 30D is marginally better. So, if the IQ overall is comparable what is the reason to upgrade? Bigger LCD? Don't need it. Besides if Canon was going to increase the size of the screen they should have increased the mp resolution. The three inch screen has the same mp as the 2.5. Nikon at least bumped their screen up to 307 mp (although they rate it in terms of dots). More fps? Don't need it. Slightly larger viewfinder? Don't need it. Now the viewfinder is much brighter, which is nice but why not give us 100% view like the d300? I can live without live view and auto ISO, both carry overs from amateur point and shoots. I don't see any compelling reason to get a 40D and in fact, why wouldn't I get the XTi? The 40D is just a jazzed up Xti and not worth the price difference between the two. There are a lot of 10 mp DLSR's out there (Sony, d40, XTi) for half the money. I'm loyal to Canon, but they really dropped the ball on this upgrade. 12 mp with 100% or near 100% viewfinder is standard in this class of camera. So I'll be sitting this one out waiting for the 50D.
