For a product Apple has given almost zero information on (Photos), a great deal of you folks are drawing all sorts of conclusions. If they release it and it's a joke, good for Adobe. But don't assume just because Photos may be a hybrid of iPhoto and Aperture that it is something to be dismissed. It may surprise.
In the end it may surprise... and if it does it'll be even more of a tragic comedy for Apple. First they scare away their potential market by announcing the killing off of a dog-eared but still viable professional app, while as you point out they have given zero-information on it's replacement. Pros or even serious enthusiasts won't accept that level of uncertainty, much less so pull another 180 back to Apple, after this same company for all intents an purposes pushed them out of the house.
As an analogous hypothetical -- lets say that Sony owned both the Wii and Playstation systems and they announced that while each is still largely successful that they were canceling both product lines and were planning on introducing single replacement for both in the future.
Beta of new product? Demo of new product? Internal/external testers for new product? -- no, no and no.
Is there a hard release date from Sony for their new console? not so much. Is release expected in a few weeks, a couple of months? No way, 6 months after their cancelation, no one has seen or played with the new console.
People are curious if the new console will be more similar to the Wii -- light and friendly or more of a power gamers console -- cue crickets.
Sony all but pushes user to buy Xbox consoles for their new games.
When finally introduced -- after maybe a solid year of silence - Sony's new console is actually pretty good, but probably certainly nowhere near good enough to entice the 100 of thousands of serious gamers that had to move grudgingly and resentfully to Xbox.
When you are a serious doing anything on a computer -- photographer, musician, writer, videographer, or software developer, the software that you get in bed with becomes part of a relationship. If your partner goes out for a pack of cigarettes and is still nowhere to be found after 6 months, the relationship is dead, or at the very least should be!
