Intel can call a tweaked 14nm "10nm" and probably will. Those designations are just marketing now. The real issues are: Will there be an even greater delay before a significant process improvement, including higher density, lower power consumption, and higher clocks? (Greater than single digit percentage point tweaks) Were billions of dollars of investment largely wasted? Will it require even more investment to get the next node out?

By the way, even if it means more delays and more money, it could still be an improvement for Intel if their previous path wasn't working well. But they would be motivated to hide it anyway because they would have hidden all the wasted time and money up to this point and wouldn't want to have to own all that.
