I was at a Meijer (major American mid-west "superstore" chain) just last week and this is what the Switch visibility is like:
A handful of Switch games stuck in the Wii U section. There is zero Switch signage, no indication that this is the new major console from Nintendo. You can see that this aisle is half blue for Wii U and half red for 3DS, with logos for both systems everywhere. Nothing advertising for Switch.
Never in my life have I seen a console launch like this, where the damn thing might as well not even exist when it comes to retail displays.
