Uncharted 4 Easter Egg - SPOILERS

So Uncharted 4 has a wonderful little Easter Egg that references the original Crash Bandicoot game. Here's the interesting thing; Activision is not listed anywhere in the credits. Whilst the original game was not an Activision game (it was Sony's and Naughty Dog's IP at the time), they would normally have to credit Activision for permission to reference the IP, just like the time Activision was credited when Crash Bandicoot was used in the book 'The Art Of Naughty Dog'. If Activision isn't credited, then either they've made a huge legal whoopsie in Uncharted 4's credits, or Sony and Naughty Dog have Crash Bandicoot back at long last. Could we be seeing the return of the loveable marsupial this year at E3? Only time will tell.
