On Friday, Sony registered domains for URLs based on something called "PlayStation Cloud", as discovered by Kotaku sleuth Superannuation today.
The domains include playstation-cloud.com and playstation-org, among others.
The domains were registered by someone from Gaikai, the cloud gaming service that Sony bought last year. Gaikai allows people to play games via cloud-based Internet streaming.
This news adds some credence to rumours that the next PlayStation will stream games.
Sony is expected to reveal the next PlayStation during an event in New York City tomorrow. We'll be there, and we'll update you as it happens.
