Man I really hope Crash 4 comes to the Switch, it looks so awesome.
I don't see any reason why it shouldn't, given it runs similarly on base systems to games that have been successfully ported like Spyro, Hellblade, and Witcher 3, and the N.Sane Trilogy sold quite well on Switch. Still, you never know with third parties.
Eh, these days you always know. Always either a shitty port or a miracle port, somewhere between 6 to 9 months later. Not applicable to very high-end games, which Crash 4 isn't.
