A few people said that the Canon EF 70-200mm f/2.8L USM lens is to be discontinued soon. They have attempted to get broken EF 70-200mm f/2.8L fixed and have been told by Canon USA that the repair for these lenses are no longer available and will not be in the future either.
Another report says an EF 70-200mm f/2.8L that was in disrepair was replaced with a refurbished EF 70-200mm f/2.8L IS II at no extra cost.
The current stock of this lens at retailers will probably be the last of them. There is no rumors for a replacement for the lens, stay tuned for more info.
