Exactly, Canon isn't trying to make their viewfinders darker, but any time you use a semi-silvered mirror you will lose light. It’s a compromise, they could of made it more reflective at the expense of low light AF performance. I’m sure the engineers at Cannon thought this was the best for performance reasons, because it sure doesn’t seem the simplest, with the added mirror and motors needed for this AF system.
That said, I still think my 40D is the best possible camera available for me, not that it's perfect, what's with the picture style and print button, does anyone use these?

That's just an assumption on my part. The coverage has nothing to do with autofocus.
And if bad AF translates into a good viewfinder, then the rebels should have the best viewfinders in the series.
