I don't want Yu to become Kojima; stuck making 2 full games when restless for a break and trying to do something new. Peace Walker was a bit of good luck--revitalized him--but then we all know too well how shitty Komani was during MGS5 and Silent Hills.
Death Stranding should've been a PS3 game around ~2009, rather than MGS4. He hadn't wanted to make MGS since Sneak Eater, and even then he first allowed others on the team to direct MGS3 before taking over after a disappointing prototype, IIRC.
At very least I hope YSnet create a fully new project between Shenmue 4 and Shen5. At least, procuring PsyPhi and finishing off the beta testing somewhere between now and Shenmue 5.
