I think there's a little confusion as to what a killer app is.

It's not the highest selling software of the year (although it can be), but rather software that sells hardware, LOTS of hardware. It's like what Wii Sports and Super Mario Bros did for the Wii and NES respectively.

those are both the highest selling games of their hardware. 

Yes but to use an example that isn't, Twilight Princess was a major killer app at the start of the Wii.  It sold very well, but not nearly what other games did.  Super Mario Galaxy, same thing.  Not the biggest sellers, definitely killer apps.
