Yeah, they did fund his last game.  And look how that worked out for them :P

I doubt Nintendo and Itagaki will be making any deals again any time soon.  As for Ninja Gaiden, I doubt they could pull off getting it to be exclusive.  Maybe timed exclusive.  

But is Valhalla Studios owned by Nintendo or did they work together just for Devil's Third ?

Last I checked, no.  They don't own Valhalla.  It was a Bayonetta 2 type situation.  Unfortunately it turned into a refresher course in the John Romero lessons.
