Nikon has scheduled several press events in different countries on August 24th, 2011. This is now 100% confirmed from several different sources. Nikon did not have any scheduled press event for the last 50 f/1.8 and 40mm f/2.8 lenses, which makes the next announcement more important than the previous two. The new Coolpix cameras may be announced a week earlier (probably on August 17th) because Nikon likes to separate the introduction of pro and consumer products.
