Can Intel work apace on their 7nm node when the previous one is behind schedule by two years, or does this derail those plans?
I'm no expert on this but I do know that their 7nm will switch to their long in-development EUV lithography process. I'd assume the work on 10nm is completely separate from their work on 7nm (there are even rumors that they'll just abandon 10nm if 7nm is ready before they work out the problems with 10nm).
Considering the troubles they have with 10nm and the fact that everyone else will have more expertise with EUV lithography than them (Intel hasn't even planned to use EUV until 5nm), that seems quite doubtful at this point.
