People have been complaining, rightfully so, about the abysmal name they gave the platform. Dude is a little delusional if he 100% believes that the name has nothing to do with it.
I mean, fuck, even Target, a major retailer partner for NOA, couldn't get it right at one point:
"Wii U" was never a name the general population looked at and thought "oh, hey, that's the new Wii". They were thinking more along the lines of "Galaxy S5 Mini", "iPhone 5C", etc. An addon or different version of the same thing. So, yeah - I'd have to disagree with him on the idea that the name had no impact and is really only something people look at in hindsight. It's been a glaring error about the thing since day 0 and continues to be. Doesn't help Nintendo struggled to even communicate in their own advertisements that it wasn't just a tablet for the Wii for a while...
