NVIDIA will show off its next-generation Pascal architecture at their GPU Technology Conference last week, where we should be introduced to the GeForce GTX 1080 and GTX 1070 video cards - with their purported cooler shrouds teased just a couple hours ago.
We could be surprised, and NVIDIA could unveil their new Pascal-powered Titan X successor - which is something I think we'll see. I think NVIDIA will unveil the GP100 GPU, rocking 16-32GB of HBM2 and a price of $1000-$2000 (I'd say $1499 for the 16GB HBM2 version and $1999 for the 32GB HBM2 card). NVIDIA could then drop the GTX 1080 for something like $599, rolling with GDDR5X - still providing a large increase in performance over the GTX 980 and GTX 980 Ti - with thanks given to the 16nm node and the new Pascal architecture.
