Where there is smoke…
The exclusivity of Crash Bandicoot N.Sane Trilogy has been a contentious matter for a very long time now. The game has only ever explicitly been confirmed and referred to for the PS4- but it has never actually been called a PS4 exclusive, under any parlance. Meanwhile, the game has continued to be listed for the Xbox One all this while, further fueling speculation that the remake of the beloved PS1 era platformers might be coming to other systems too.
Add Nintendo Switch to the platforms it could come to- according to Keymailer, a site that assists YouTube and Twitch content creators in getting review codes, a Switch version of the game is inbound. Do keep in mind that this is just a listing- it could well be erroneous, and mean absolutely nothing. But given the business of the website here, as well as the context of Crash getting so many leaks for other platforms, I am personally inclined to believe this- though I would advise exercising caution and taking this with a healthy helping of salt.
Crash Bandicoot N.Sane Trilogy is currently available only for the PS4.
