Dream Lens announced!

Canon just anounced EF 200-400/f4 IS lens! It's dream lens for wildlife and sport photographers. Moreover Nikon had such lens for many years and Canon had only 100-400. Of course this 200-400 will be expensive! I expect it to cost about 6.5-8k USD, so it's not for amateurs, unfortunately :(

Actually I've figured out that this can be called EF 200-560/4-5.6L IS lens, because you can turn on 1.4 extender on 400 and you got 560/5.6L IS!!!! They made few lenses in the one! Only the price is unknown and probably not very low...
