As far as I know there is no reason to think that Intel's problems with 10nm process have effect to new processes they are developing for 7nm. Core technologies change and missing a step is something that might happen to others in the future.
In fact GlobalFoundries also failed their 7LP (7nm). As a result they stopped pathfinding and research for 5 nm and 3 nm and quit the race. They are moving to more specialized chips.
Fab cost for new process has grown each year for decades. Now it's something like $20 billion. Stakes grow at same time as things get more hairy and complicated 'down there'.
