I think sucker punch are making Metroid 4.
They're essentially done with Infamous.
They are working on an unannounced title.
Infamous has similar designs as Metroid, gaining more abilities
Sucker punch worked on sly trilogy which would fit right at home on a Nintendo console.
I think my math is sound.
All it would take is Sony recognising how good the Switch is and letting Sucker Punch make games for it lol
