Agree that the smite button needs to be done away with... Positive karma is cool though.

Due to popular user request, I think they should switch to a yearly cycle just like in software: 50mm/1.4/2011, 50mm/1.4/2012, ... so people will have plenty to rumor and discuss about. Or they could do it like car manufacturers: change the color, tweak the design of the af-mf button and so on :-p
This shows where the 135mm f/2L MTF chart stands against the MTF chart of Canon's top performing prime the 400mm f/2.8L IS II. Two completely different lenses, of course, but it shows just how remarkable Canon's current lens technology is, and how much the 135 could be improved. In simplified terms... the higher the lines and the closer they track each other the better the quality of the lens.
Keep in mind that the black lines show the lens wide open while the blue lines show the lens stopped down to f/8, so the closer these sets of lines are to each other the better the performance of the lens when used wide open. The very best lenses will have the black and the blue lines close together.
Generally speaking a lens whose thick lines (10 LP/mm) are above .8 on the chart should be regarded as having excellent image quality. Above .6 is regarded as "satisfactory". Below .6 is, well, below.
[...] The closer [the dotted meridonial and sagital] lines are to each other the more pleasing the bokeh of the lens. Fascinating, huh?
The meridonial and sagital lines are also used used to evaluate astigmatism and field curvature — subjects which are beyond the scope of this brief essay.
"It's not a question of whether or not you have a mirror. There is a consumer need for good-quality cameras to be made smaller," Maeda said. "We will meet this need."
He denied this would be difficult without removing the internal mirror, adding that Canon had produced very small SLR cameras in the past.
going back to a previous discussion if they made it say a 25MP APS-H that shot say 5 or 6 FPS in H mode and 10FPS in crop mode at 15MP and be able to use EF-S lenses accepting the vignette in H mode vs C mode
it would be totally awesome.
Really though, this isn't that hard to predict. Too many people get caught up in what they want companies to do, instead of looking at what they are doing. An objective examination of Canon's recent actions points pretty clearly in this direction.
