I don't think it's been confirmed yet that he has left or if anything has really happened there, but Sony would give him excellent creative freedom.
I wonder if Kojima could afford to buy out Kojima Productions? He has to be worth a fair bit, maybe he'll buy the company from Konami and just do his own thing.
Sony could probably buy Kojima Productions and add them to their roster of developers.
I think the Internet would explode if that happens, even if Konami kept the rights to Metal Gear and Kojima didn't own the series to use the title as a Playstation exclusive.
