Crash Bandicoot N-Sane Trilogy was confirmed to be a PS4 exclusive by PlayStation Ireland. “Was” being the keyword because the tweet was quickly deleted.
So now the question remains, is it an exclusive? Most likely. PS Ireland hasn’t followed up with a response, so chances are, they jumped the gun because they haven’t officially apologized yet. Activision still holds the rights to the series, and they have published multiplatform Crash games before.
Regardless, the game is still slated to release June 30.
