Then, Photoshop CS7 for instance will install in a separate directory?…
No, there will be no Photoshop CS7 at all, ever. There will be no upgrades to the perpetual license of CS6. CS6 is the end of the line. It will continue to work just as it is, as long as your OS suppurts it; but there will be no upgrade versions from it.
For me it is absolutely the end of the line. I will not be adopting the CC thing.
I think I understood you on that, just phrased it differently. IE I have CS6 Extended now, and since all updates are now handled through Adobe Application Manager, I was a little hesitant to download the updates, thinking my CS6 might get "upgraded" to CS CC, and would therefore be unusable as soon as my subscription expired.
Thanks for the information.
