New Canon Telephoto Lenses

I just read a post that Canon will be displaying two new telephoto lenses at PhotoPlus Expo in New York next week. These lenses are the EF200mm f/2L IS USM and the EF800mm f/5.6L IS USM. The EF200mm is of interest to me because of the type of work that I like to do. The EF800mm would probably be of interest to those who do sports and nature photography. Potential prices of these lenses are yet to be determined.
