D you really think with the continuous advancements in AE NUkE will be here in 2016? I can name 20 highend tools from 12 years ago that have EOL'ed. Even the 35mm camera has been EOL'ed.
No one on here has used Smack 2013.
Realtime is relative to the type of clients you have.
The rendering in Smoke is extremely fast and non-destructive. Its a non issue. It does not decrease the quality of your image in any way whatsoever.
Nuke is a great shot to shot tool no question. Most of us don't work in pipeline efx chains. We are small studios centered around the Red cameras. We don't limit ourselves to any one technology as in A is better than B. If we have jobs that need A or B we send them out. 49% of effects, CC, Audio, media management, and finishing work can be performed on Smack. hopefully now we can even edit on it.
There are a host of other very capable tools like the Adobe CS master collection and fcp3. Its almost a must to have these in you studio. Honestly the most difficult part of smack is or was the interface. I use it all the time along with the CS products, but I have to visit Grant Kay's blog to figure out each step to a new vfx challenge. I find it much easier to do graphics and effects work in smack than in AE. keying, cleanup, removals, rotoscoping, etc is a breeze and fast. After pulling a traditional key, the 3D space inspires you to create elements you hadn't initially conceived. There's always a new light you could drop in a scene, add a spring sky, make elements appear and disappear because of the roto-tracking speed. I cant wait for CS6 and Smack 2013. I don't use media composer, and i sure as hell don't have an interest in fusion, pablo, mystika, or DS.
