There's something going on at Konami that we don't completely understand.
Konami appears to have added references to Hideo Kojima back into the websites of some Metal Gear Solid games. Konami had removed Kojima's name from all things Metal Gear recently, following a corporate restructure.
The changes were reported by Videogamer who posted before and after images. Metal Gear Solid: The Legacy Collection and Metal Gear Solid 3: Snake Eater 3D have had their cover and description change to mention Kojima's name again.
Both Ground Zeroes and The Phantom Pain have not yet been updated.
As you can see at the top, the cover art for The Legacy Collection now features Kojima's name.
