40mil install base vs 1.4mil install base. What do you expect? Every ps4 and xbone owner to buy a new game every week?
Typically all the people who just bought the console and a tiny percentage of the install base that hasn't recently bought a game buy a game every week. This is why it makes complete sense that ps4 and xbone software has completely fallen off.
The vast majority of the million people who bought the new consoles the first few weeks are not gonna buy any new games for a while so most game sales will be from people who just bought the console the past week or two.
Remember guys typical end game tie ratios are 10 games per console and thats after 8 years. People buy much fewer games then you guys expect.
Wii U software sales are a bit higher because a significant amount Wii U owners haven't bought a game recently while virtually every xbone and ps4 owner have recently bought games. Not to mention every Wii U comes bundled with one game or another that vgchartz counts towards these sales.
