Nintendo didn't leave the casuals, the casuals left Nintendo when they realized they can pay a couple bucks a pop for their entertainment on their smartphones rather than $250-$300 on a console and $50-$60 a pop for maybe one or two games a year.

Wait..what?

It doesn't need much explanation really.

 

Wii attach rate is under 9 games per console.  Divide that by how many years Wii U has been selling.

 

That includes the folks who buy 50 or 100 games, so the most casual of players have less than that.
