Sony should pay From Software to try their hand at a Monster Hunter clone.

I would rather they make another Tenchu game. Souls-style.

It could be a Souls game with emphasis on stealth. I mean think about it: Demon's Souls and both Dark Souls are clearly defensive games. Bloodborne is clearly offensive. What's next?: Deceptive. Yes there will be combat, but generally frontal combat would be a last resort. Instead you would position yourself so that you can stealth kill enemies.
