The site explains the gaming lineup from NVIDIA is on a "Tick-Tock" like cadence and that the next GeForce lineup will be more of an incremental gain. Using this point of view, Pascal was the "tick" whereas the next lineup will be more of a "tock".
Based on earlier rumors, it seems certain that NVIDIA's next GeForce lineup will use GDDR5X memory and that the chips will be made on TSMC's 12nm process. The 12nm node is basically an enhanced version of the foundry's 16nm node.
The dedicated follower of Pascal is now "a Pascal influenced design derived shrink down". With Maxwell architecture, Nvidia chose to optimise the GPU for better memory management. Back then, it became apparent to Nvidia that HBM and HBM 2 would not become mainstream in time for Pascal. Fudzilla already mentioned the fact that Pascal follower will not use HBM 2 memory.
