Nintendo always sues when their IP is used in fan creations. I don't see this as any indication that they'll be doing anything on iOS. Nintendo rarely does anything with 3rd-party platforms.
If Masuda is involved, it's probably Pokémon Gray, RS remakes, or something for 3DS using the Pokédex 3D graphics engine we previously concluded was more than meets the eye.
