EA has brought two FIFA titles to Switch and that's it. Some might think the publisher doesn't really want anything to do with Switch, but a LinkedIn profile for an EA employee might show differently.
The LinkedIn profile in question is for an EA software engineer, and it shows he's working on bringing existing SDKs to Switch. While Frostbite isn't mentioned, the developer does say that he's worked on SDKs that have been used in both Battlefield V and Anthem. Both of those games utilize the Frostbite engine.
EA has already made their own engine for FIFA on Switch, which they talked up quite a bit. To see them move Frostbite over for another installment of FIFA doesn't make too much sense, but it could happen. Hopefully if Frostbite is coming over and being used for FIFA, it will at least pave the way for other games as well.
