If anyone can save konamis ips is definetly Sony. But there are smarter purchases available. Sonys talent is key here. They could buy smaller to mid tier studios and expand them with the adition of some of their senior staff of some of their big studios. It would cost them a lot less and they would have new ips wich are more desirable and probably get quality right off the bat.
It takes genuine talent to see greatness in yourself despite your absence of genuine talent.
