Don't all EA games run on Frostbite now?
One of the developers said that they could have had Frostbite on the Switch for Fifa 18 but they didn't because they felt like a custom engine would be better for it in an interview by eurogamer.

So I think EA is waiting to see if Fifa 18 sells well on the Nintendo Switch before bothering to put the Frostbite engine on it and then they can port more games over to it. I'm guessing they probably don't wanna waste time porting the engine for the Switch unless they know they're gonna be able to sell games on it.
