Before this quote gets blown out of proportion the only thing Iwata actually said is this:
“Certainly I’m not satisfied with the current situation,” he says. “It may not be [people’s] first console of choice, but they recognize it as perhaps the best second console,” he adds.
He didn't say anything about NX or how NX relates to Wii U, that is speculation on the Time writer's part.
The only thing he said about NX is that
1.) It's a dedicated game platform.
2.) It's a "brand new concept"
3.) He can't say anything else about it until next year.
