Just to make it clear (I edited) I didn't mean by launch, but for 2017.50,000 is a very unrealistic target, only titles like Mario Kart 8 Deluxe or The Legend of Zelda: Breath of the Wild can do that and not by much, but it should have definitely done much better than barely 8,000 units, also Switch install base is far from half a million units. To put things into perspective FIFA 14 sold more than double one week before PlayStation 4 was released.
If retailers saw enough demand for the Switch version EA would have shipped more. There is more to it then just saying well EA should have printed more copies.
It wasn't open for preorder. So where would this magical demand come from?
