Kojima had been working on games since Peace Walker released and had little to nothing to show for it.
Zone of the Enders was a non-starter. No sequel, just a re-release that ran like ass.
Rising required an entire retooling by platinum.
Silent Hills released as a free Public Teaser and was the closest thing to impressive.
MGSV was unfinished and shoved out the door.
That's just Kojima. Then you just look at the other products and you'll see that Konami was shooting themselves in the foot. Pretty much every Silent Hill after 4 has been meh and the last peak of the series was 2. The SH HD collection was abysmal. Castlevania lost the luster and sold like shit before being put in the grave by LoS 2.
Even with Kojima's draw, Konami is just fucking up way too much to stay in the vidya industry. They're cutting too many corners, while also managing a host of series that had long since lost their popularity. ZoE is not going to move units equal to any other triple-A game. Nor is SH anymore (although PT for once did something right). Neither will Castlevania.
