Nintendo needs Polaris 11. It matches everything they do. Low wattage, 2.5 TFs, and a good price. And if previous 'leaks' are true NX is hovering around 12GB of RAM. It'll be quite a potent little box for what it does. They just gotta price it right. Use a regular controller and sell it for $199 and you got a instant seller that is powerful enough to last a few years.
Then release the SCD and NX will be around for a long time.
