...If, and it's unlikely, cc manages to quell privacy, all you'll see is gimp take off, pixel actor we'll even better, and in cases like mine, I bought perfect photo suite which does most of what I needed to do in photoshop, by giving me layers, masking tools, etc. ...
I really do hope development for similar products picks up as I don't intend to give Adobe any of my money in the future, not for a cloud based alternative anyway. I paid good money for Photoshop in the past and I'll keep using that as long as I can, then I'll try the options such as those you've listed, but I won't 'cloud'.
I'm not a big Photoshop user anyway, been happily using CS2 since it came out! All I need is layers for compositing images, the rest I can do with other programs. I hardly ever use Photoshop since the later versions of Capture One as everything I do is raw.
