Current Model Canon Super Telephotos Leaving the Shelves

The current Canon super telephoto lenses are leaving the store shelves. Not as in going out of stock (yet), but as in people deciding that the current models are excellent and, while expensive, far less expensive than the version II models.
 
Going out of stock is going to happen for these lenses at some point. If you are considering adding a super telephoto lens to your kit, consider buying now.
