Paid online gaming will help control some of the losses, rumoured to be $60 per unit.
Sony has confirmed that the PlayStation 4 would be sold at a loss with sources for Eurogamer stating that it could be as much as $60 dollars for each console, which retails for $399. However, Sony Japan executive Masayasu Ito stated the company is looking to recover on those losses via paid subscriptions for PlayStation Plus, which is now required for playing online, and with its launch titles.
Ito denied the accuracy of $60 loss figure. He also neglected to mention how many launch titles would be helping to control the loss, but stated that the console will be making a profit faster than the PlayStation 3 did (which took several years after launch to finally see some semblance of profit).
Nonetheless, if the figure is accurate, will a PlayStation Plus subscription be enough to help control it? That depends on how many people would be willing to pay for online gaming, but considering the state of Xbox Live, it should be fine. The PS4 launches on November 15th in North America and on November 29th in Europe.
