At this point, Intel has basically come to accept that it needs to redefine 10nm to be whatever meaningful improvement over 14nm it can manage to ship by the end of this year. I'm not sure what exactly this will entail, but I'm sure that there are enough usable ideas from their failed 10nm that they still have a significant advance over 14nm. Even if the fab process ends up not being much of an advance over 14nm, they have a backlog of microarchitecture changes waiting to ship on their first post-14nm process (eg. LPDDR4 support, GPU improvements leading toward their discrete GPUs).

Their 7nm process is quite different and the biggest potential roadblock there is EUV, which is the same potential roadblock everybody else is working against.
