This comes from the PS4 section of GameStop's website, and the url of the image still works but it seems like they removed it.
However it's still in the Google Cache of it:
As a reminder, Crash (and likely Cortex) are playable in ALL versions of the game, including the Wii U and Xbox One versions. They are just likely timed-exclusively available in the PS3 and PS4 starter packs (I imagine Cortex is in the PS3 box as well). and will get standalone releases later, as did DK and Bowser with Skylanders Superchargers (however they obviously only work with the Wii U and 3DS version), and as another reminder, DK and Bowser are confirmed to work in Imaginators also.
Edit: Enlarged it 2x if it helps:
