First off I want to apologize for the extended silence on my blog. After spending a month in the Candian Rockies I came back to a full plate at work. I still have about 4000 images from my trip and two entire Yellowstone trips to edit and get online for all of you. I am working on it.
Now for the reason behind the post... Canon has lots of new glass and I wanted to share the news.
Canon's site with all of their glass, new and old, is here:

dpReview has all the news items from Canon, and other PMA announcements, online here:

The biggest news for me was the weight on the new 400/2.8L IS II (8.5lbs).

I am going to be taking a hard look at this lens and will likely sell my 500/4.0L IS to make the upgrade.

Update...
I wanted to give everyone an update.
The 300/2.8L IS is SOLD (I hope it is as great for you as it was for me David... Enjoy).
The 70-200/4.0L is still on the market. Let me know if you are interested.
I got the 50D and grip back from Canon today (I think yesterday actually). They fixed and cleaned both and gave the both a clean bill of health. I guess that is good because when Canon comes out with the 60D and I get my hands on one both of those pieces will be for sale.
CPS did a great job fixing and getting my gear back to me. I only shipped it out ground on Tuesday night. Canon in California got the package on Friday, and I had everything fixed and back on Tuesday. Great work CPS... If you qualify and are not a member you should be.

Diffraction
A great essay on Luminous Landscape by Nathan Myhrvold.
The full essay is here.
The quote that really explains the flip side of diffraction limitation is:
We all know that lenses are, more often than not, becoming a hindrance before the physical diffraction of light, especially with wider angles of view. Most lenses get worse as you cross f/8.0 while 21 megapixels (35mm - full frame) suffers from diffraction around f/11.
So does your crystal ball look like you will have a 21ish MP camera with your wide angle set to f/11 while you have your 200-400/4.0DO HIS (dreaming) on a 50-100MP high speed camera and you just don't stop your lens down bellow f/6.4 - f/4.6?
Also remember that the 50D already has the pixel density of a 39 megapixel (35mm) full frame camera.
The only thing we know for sure is that the future will be interesting.

The quote that really explains the flip side of diffraction limitation is:
The diffraction limited aperture for 100 megapixels / 35mm full frame size is f/4.6 , 50 megapixel is f/6.4 . There are plenty of lenses where a 50 or 100 megapixel sensor will show some benefit. Indeed most macro lenses work well open. So do many super-telephotos like 300mm f/2.8 or 600mm f/4 – they are typically used wide open where there would be no problem with a 50 to 100 megapixel sensors.
We all know that lenses are, more often than not, becoming a hindrance before the physical diffraction of light, especially with wider angles of view. Most lenses get worse as you cross f/8.0 while 21 megapixels (35mm - full frame) suffers from diffraction around f/11.

New Canon Hybrid IS
I am sure that you have all seen this by now. I came across it late last night and was instantly glad that I have waited on trading my 300/2.8 for a 500/4.0.
I can not stop thinking about how Canon said that this fall would introduce 100 new products, and how they said that 2009 and 2010 would be the years of new lenses. Think about all the lenses that came out 10 years or so ago.
Nikon just got VR in lenses that Canon has had for quite some time. The VR is about equal to what Canon has. And now it is time for Canon's next step and that next step could be very cool.
The release is online here.
From Canon:
New Canon Hybrid IS world's first image stabilizer to compensate for two types of camera shake
Angle camera shake
Shift camera shake
TOKYO, July 22, 2009—Canon Inc. announced today the development of Hybrid Image Stabilizer (IS), the world's first* optical image stabilization technology that compensates for both angle camera shake and shift camera shake. The technology will be featured in interchangeable single lens reflex (SLR) camera lens planned for commercial release before the end of 2009.
Several different preventative methods and corrective procedures have been introduced to compensate for errors caused by camera shake, which occurs when a camera moves while its shutter is open and its image sensor is exposed to light.
Canon began researching methods to compensate for camera shake in the 1980s, and in 1995 launched the EF 75-300mm f/4-5.6 IS USM, the world's first interchangeable SLR camera lens to feature a mechanism that compensates for optical camera shake. Since then, the company has continued to produce a variety of interchangeable lenses with image stabilization capabilities, and boasts a total of 21 such lenses in its current product lineup.
Canon's newly developed Hybrid IS technology optimally compensates for angle and shift camera shake. Sudden changes in camera angle can significantly alter images taken during standard shooting, whereas shift-based shaking, which occurs when a camera moves parallel to the imaging scene, is more pronounced in macro photography and other close-range shooting.
The new Hybrid IS technology incorporates an angular velocity sensor that detects the extent of angle-based shaking and is found in all previous optical image stabilizer mechanisms, as well as a new acceleration sensor that determines the amount of shift-based camera shake. Hybrid IS also employs a newly developed algorithm that synthesizes information from the two sensors to make optimal adjustments, thereby dramatically enhancing the effects of image stabilization during shooting, including macro shooting, which had proven difficult for conventional image stabilization technologies.
Canon is actively engaged in ongoing research and development of interchangeable SLR camera lenses incorporating Hybrid IS technology, and is aiming for the early commercialization and inclusion of the lenses in a wide range of products.
