Niko Partners analyst Daniel Ahmed went into more detail about this on Twitter yesterday:
“If a publisher wants to put a game on a 32GB cart on Switch it costs 60% more for them then it would for a 50GB Blu-Ray on PS4/XB1. Your game needs to be less than 8GB (because 8GB carts are cheaper) if you want to make the same margin as PS4/XB1 Blu-Ray disc.”
