Activision is not the type of company that creates exclusive games and the Crash Bandicoot Trilogy released some weeks ago, could be ready for another systems aside PS4.
Kara Zisa, artist at Vicarious Visions, was the person responsible for the save/load screens on N. Sane Trilogy. Kara updated her portfolio with a video of the game and the clip included the Xbox button scheme in the whole footage. Therefore, the remastered trilogy of Crash could be in works for Xbox One, or maybe for a PC, or maybe for both. There is another scenario: N. Sane Trilogy could have been in development during a concrete time, but not now.
One way or another, the release of this platformer has been rumored before, so there are chances to play it on different systems than PS4.
