FIFA 20 is supposed to be a watered-down version on Switch. This already shows how little interest EA has. Of course sales will take a dip because seriously, why the heck are we gamers supposed to be excusing laziness? We are not. Then, after this edition they will either stick to their watered-down versions or just bail out entirely. And it goes without saying that FIFA will be the only thing that will ever land on Switch, if at all.
Personally I despise EA and consider this rather positive news. I want them to stay away as far as possible.
