What is is about CS6 that means you can't use it in the long term? I can't imagine what features could be added to the programme that are so radical people feel it makes CS6 redundant. If one can produce great images with it now...why not in a decade?
(although, I think you may have meant "obsolete" vs. "redundant")
You could put me back on CS3 and I'd still be able to do the same things I most frequently do in CS5 or CS6.
Sure, 32 bit would be slower, and there would not be content aware and a few bells & whistles, but the salient point @ the fundamental tools are relatively unchanged ... what in the world could CS99 have that you don't already have on CS5.5 or CS6?
Sure, ACR versions may update and new camera/new lens correction updates might not be there ... but for updates and ACR ... stay current @ LR.
But, if you really want to migrate from PS because of $$$ ... Corel Paint Shop Pro X (PSP) worked for me before I upgraded to PS @ CS3. If it wasn't for the primary reason that PS offers LAB and PSP doesn't I probably could have still remained on PSP. Now that I've learned to harness more of what PS offers and I'm a bit engrained to the PS workflow ... I'll simply stand pat on using my CS6 tools. I really can't envision why I'd need anything else that they could possibly add to PS.
Everybody's bent at Adobe ... but imo, you have to ask yourself, what is it that you really need from your tools. You've lived your entire life without the next "bell & whistle" that they're gonna put in PS through the cloud or CS7-CS99, and as far as I can tell, PS is so mature that the only thing left to do is change the window dressing or toss in a bell & whistle or two.
My guess is that Adobe probably knows there isn't much left for them to change/improve and has realized that not many folks would buy CS7 because it can't be that much different from CS6. So, rather than wait to see CS7 sales be even flatter than CS6, the subscription route is the model. But, Imo ... we'll need updates from the subscription about as much as we need CS7 ... i.e. we don't.
But people are "scrambling in fear" that they might miss out on something they've never had and jumping on the bash bandwagon because it's more satisfying than accepting the notion that you'll still be driving the same old car (CS5/CS6) a year or two from now. The emotion of Adobe taking away our options is driving people nuts and they are abandoning the logic of what it is they actually need faster than people were leaping from the Titanic.
If you truly like/need PS and the tools it offers ... probably not too much to think about. If the cloud thing is your biggest issue, you're talking about $$$, not tools. Many of the tools I have in my garage will last me a lifetime ... no matter if they do come out with a new & improved lighter, stronger more $$$ hammer. But, I'm not so sure the nail will know the difference.
