It's not like Nintendo has given any confidence that they are learning anything recently. The last time they've spoken to the public, they made themselves look stubborn and delusional once again. By doing a straight follow up to one of the currently most hated Nintendo games, Sticker Star. Doing a finebros-esque damage control video to make Metroidfans look stupid (could have simply scratched ,,Metroid" from Federation Force instead). Trying to rip people off with a new Virtual Console service yet again, despite finally offering ,,accounts". Believing the laughing stock Project Guard is actually worth being a separate product, instead of being completely tied to the already poor looking Starfox.
All that would actually make me believe that they'd stubbornly continue the second screen concept despite its obvious failure and rejection in the market. But then it also wouldn't be a stretch to think it's gonna be as dumb as it looks.
