What has to be understood is that "making a stride towards 10nm" and "relaxing the design so it looks more like 12nm (by Intel standards)" are not mutually exclusive and I bet they are both true. The goals forced by Intel higher-ups for the 10nm process were ridiculous and didn't have much to do with having a 10nm process, but having a denser 10nm process. When we first heard about them at SemiAccurate, everyone except of Intel execs and investors pretty much knew that they are not tangible, at least not as the next, quick step from their 14nm node. In that regard, the SemiAccurate "predictions" were considered to be obvious there.
If you look at TSMC, they had a 10nm process but the Intel 10nm process would be denser, to the point it would in practice be like TSMC's 7nm process that scales even better for high-performance chips.
After all those years, I think they realized that they had to relax the original requirements to release the process after all. As a result, I think we will simply see a "less-than-expected" 10nm process by Intel standards, but it will be a 10nm process nonetheless. I think the relaxed design requirements will simply mean that TSMC will have an edge here for the first time, or at least be equally competitive. Maybe 10nm++ or +++ will be closer to what Intel originally wanted. I'm 99.9% sure that's exactly what Intel is doing now.
