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).
