There is no time for rest on the rumor front!
Olympus will announce new PEN cameras in September along the black version of the current 12mm and 45mm lenses (surprise, no black version of the new 75mm lens).
Samsung meantime keeps working and changing the lens roadmap. Instead of the planed 55mm f/1.8 we will very likely get a iFn 45mm f/1.8 pancake. That lens and the new iFn 30mm f/2 version II and the 12-24mm f/4 could be announced in Photokina and they would be available on Q4/2012. All lenses will be announced along the new NX camera.
