Since the game didn't get any spotlight in recent PS events, it's likely to be a small game, but i'm looking foward since japan studios can create some amazing and fun games!
Trolls will talk about knack, but Japan Studios can create great games like SoTC, Astrobot, Gravity Rush, last guardian and many others. Also they got major participation in great games like Bloodborne and Demon's souls.
Prediction: In 5 years Nintendo will Lauch a "Core Mario game" very similar to Astro Bot. That said, many will Ignore Astro Bot existence and say Nintendo created this concept.
