I don't think the Wii-U has lost solely because of it's hardware. Nintendo didn't lose third party support because of weaker hardware; they lost in because of a complete lack of interest in third party titles from Wii-U buyers. Another factor is Nintendo's poor online service that barely competes with Sony's original PSN model on PS3, in terms of features. That, and Nintendo's fear of upsetting mothers of America took their toll. Let's not forgot that a more powerful Wii-U would've costs significantly more, and it really wouldn't have paid off much, as most Nintendo first party titles have never had any real justification for crazy realistic graphics. What's already there suited their needs perfectly.
