What you think that NoA could make? Wii U is a terrible and expensive console.
Yeah, the major problem comes from NCL itself, which released a product that wasn't able to result as attractive in the first place to the masses, especially with the initial price and lineup.
...Although I'd say the low amount/quality (especially quality) of commercials when it launched had a part in that. But it's also true that it wasn't all NoA's fault (quality surely was, though).
