It looks like Panasonic and Samsung will still announce some new mirrorless stuff in mid-late July! While Panasonic announcement is scheduled for July 18th (G5 and 45-150mm m43 lens) we have been told that Samsung will announce new NX lenses too! There will be three new zooms, 16-80mm, 12-24mm and another 50 (or 55?)-300mm.
I guess that stuff wouldn’t get that much of press buzz when announced at Photokina. That’s why they prefer to launch the stuff in these hot summer.
