Not everything is negative
The xxD line of cameras was expected to be on a 1 year product cycle after the launch of the 50D a year after the 40D.
One more person piped up this evening and said everything isn't doom and gloom. Still expect a 50D successor sometime in the fall. The 40D will be done away with and the 50D will remain a current model. There was no information as to whether or not it would be a APS-C camera or not.
