I might be talking out of my ass here, but doesnt it take longer than a couple of months to write a killer app like that?
When Aperture 1.1 hit was released earlier this year and Apple announced a serious pricedrop it was rumored that Apple was about to discontinue Apperture. Can it really be that Apple in 6 months or so since the last release has made such increments that it really call for a presentation at Photokina of all places??
That strike me as highly unlikely, considering Aperture in the first place was very limited compared with e.g. PS.
My best guess is that Apple is about to release something else... but I don't have the slightest clue what that could be.
Whatever it is, it has to be big to make a splash at Photokina since many big releases are expected there. The biggest of the all would be Leica M8 digital.
