With Nintendo fixated on the "power isn't everything" perspective, where they really messed up was on the pricing of this thing. As I said in another thread, consumers are smarter than ever these days, and with tech sites, fellow gamers, critics etc all saying Wii U is not much more powerful than PS360, its simply not worth the upgrade at that price point. They should have made deluxe $250-299, & would have flown off shelves. Nintendo should have been more aggressive with the pricing, and like Wii could have been a stable price for a good while, PLUS would have stolen PS360 holiday sales. Nintendo gambled, got greedy and failed during their launch window.
I think there is plenty of interest & curiosity, but not at that price, when again, universally in the gaming world "there isnt much power difference with PS360" other than some minor efficiency gains/modern features of gpu.
