Historically the two consoles didn't launch within a week of each other, with the more powerful system being ... cheaper.
At the risk of comparing apples with oranges
Im not a big Apple fan, but... isnt Apple products typically less powerful in terms of raw power when compared with some top Android phones? So why Iphone / Ipad / etc are incredibly successful? Maybe raw power is not the only, and not the top reason that consumers considers when choosing a platform. Maybe its just one more variable, among others (price, quality of services, exclusives, deals, controller, etc)
