Does Wii need to outsell PS3 + 360 to lure 3rd parties?

Look I am not saying that PS3 + xbox360 is selling worse than Wii. I am saying that software sales on Wii is good and if you make an effort you can strike gold.

 Problem is most of them don't know how to do that.  They build these high price next gen engines, they have these big game ideas for these powerfull HD consoles games.  What they hell are they supposed to make on the wii ?

Nintendo is screaming casual gamers causal gamers from the roof tops but 3rd part are not great at making games for that demographics.  Wii is a scary unknown weird dangerous thing for them, Ps3/360/PC is safe.
