Well, for one, blaming Shu for game delays would be like blaming Trump for how long it took to get your lunch at trump hotel.
Shu is involved, yeah, but Shu doesn't personally oversee operations. There are probably like half a dozen managers and directors at every studio, and then district supervisors, and regional directors, etc, etc.
Second of all, he's probably well aware that their games are delayed a lot. It's common practice to overpromise on timelines because it's part of the overall strategy to announce and control information. That Hideo Kojima game isn't probably even thought out, but they made a video for it because it's a HUGE announcement. They don't care when it's out.
tl;dr
sometimes, it doesn't matter when your games come out, because for the majority of people, a console is sold on its POTENTIAL, rather than its current offering.
