A possible reason 3rd parties ignore the Wii...

That's some good information you put together. I never realized how poorly the 3rd party software sold on Wii.

Everyone looks at the massive sales of Nintendo's first party games and assumes its a big software mover, but in reality its not. Only the well known franchises (like Guitar hero, and the big Nintendo franchises) have great sales on the Wii with of course a few exceptions

And keep in mind the Wii has over double the PS3 userbase and its getting owned!

 

Dude he only put the top ten sellers on the big three consoles third party wise and even left out SEGAs top seller on top of it.  Nintendo Wii killed the other two consoles in third party software sales last year (with little quality support) and it shows with the support they're finally giving Wii this year, period.  You're taking the OP completely wrong.
