This is really not a good comparison. No More Heroes got hardly any advertising on both the 'HD' systems and Wii and wasn't expected to sell well either way. And if you look at your own data, it sold about the same on all the systems. The difference of 2,000-4,000 units is microscopic.
Now, if the title had come out for the HD systems with heavy advertising and hype and then failed to sell better, then the games would have 'underperformed'. But they didn't. They sold about the same.
This is in contrast to something like a Multiplatform title such as LEGO Star Wars or The Beatles: Rock Band which clearly sold better on Wii. That is the only time you can really make a direct comparison. When the same game is released at the same time on all the platforms.
