Hmm wondering if 6gb is enough for 4k SC.

Likely yes, as there have been several people with Titans who had solid performance, could stand to have more GPU, but, they were not bottoming out the RAM until they were hitting the AA pretty hard.  But 8gb I think would be preferred so you ahve a bit more buffer as newer games come out, and also so you can mess with AA or other settings with a bit more freedom.

Now the real question... will this release before my stepup is over lol

Welcome, welcome dear NVIDIA. 
You will not betray you loyal customers. 
Again will be winners in premium class, I FEEL! 
Now Jacob only need to reserve best chips for best partner. 
EVGA deserve that because it's specialized for NVIDIA cards and no other partners and all earning depend from NVIDIA 
and because treat customers good and many times prevent to someone cross on AMD because driver or similar problems.
 
6GB is enough only if NVIDIA not cut some other things.
I would go example on 6GB version if EVGA prepare card with same clock for 6GB and 12GB.
If 12GB stay for reference board and Titan Successor and 6GB for GTX980Ti or some other name with same number of CUDA that would be fantastic and even for OC probably better model with 6GB. 
 
 

What I would love to see in the next GPU generation:
 
1. Wider memory bus
2. More VRAM
3. Reduced coil whine
4. Reduced temps

Although all this is very nice, but HBM is a major advancement which will increase VRAM since you can get more into the same place. I wish this was another item which may be available, then the increase necessary will become reality.
