I semi-agree, though I would say the problem with the Wii U is the LATER years of Wii..
I definitly think people's trust in Nintendo has been shaken after the last couple years of the Wii what with the brutal dry spells. Hell even me, a lifelong Nintendo fan, isn't even considering buying a Wii U until at least the end of the year, and I've only JUST purchased a 3DS. Part of that is the lack of third parties but not all of it. Nintendo simply stopped making games for Wii far too early IMO. After NSMB Wii in 09, there really wasn't a whole lot else.
However, all hope is not lost. If Nintendo cranks out enough games, sort of like they are currently with 3DS, eventually the consumers will follow. They need to focus less on 3DS, as it's got a sufficient amount of games and third parties are stronger there, and focus WAY more on Wii U. They also need to focus on landing some more 2nd party stuff to help fill in the gaps, similar to Xenoblade, Last Story, Retro, etc. I think third parties are too stubborn and scared of going up against Nintendo games so that's not really an option at this point, but I do think they can do a lot more than they are doing as far as 2nd party software.
