NeDa is going to develop these games. Nintendo still make games for their own hardware.

It's perfectly possible to do both things.

They will be jointly developed. Most likely Nintendo will design the core gameplay to ensure good quality and then DeNA will be responsible for maintaining the content back end of it (ie: daily updates, leaderboards, online play, microtransactions, new DLC content, etc.). 

They'll probably supervise these things, but they already have studios for that (Nintendo SPD).
