It's not looking like anyone will use 20nm, I think they'll both be 28nm and we'll get 16nm this time next year as TSMC have said Q2. What I think will happen after that is 16nmff+ will provide a mid-gen further shrink. It's supposed to come about 6 months after. Perhaps we'll see HBM gen2 on those products.
So in early 2016 you would have 490X HBM going up against Pascal HBM/HMC both on 16FF+ and be looking forward to 10nm where hopefully some REAL tangible benefits can be seen, expected to begin tape outs end of that year.
