I think this is so weird. We keep getting quotes in statements like "Xbox One and PS4 showed 30 percent growth YoY" and "Xbox and Playstation are now at 90 million consoles sold" etc. Is the Wii U and/or the Switch not consoles? Why are they separated from the pack? Either lump everyone together, or not at all! Just singling out those two is like giving two-thirds of the class a gold star when everyone participated. *shrug*
This kind of data obscures the performance of individual platforms anyway. But, what's the purpose of only mashing Xbox and Playstation when Nintendo is still a big presence in the industry?
