Engadget: "Indeed, the Xbox One will load disc-based games onto the hard drive automatically. Both Sony and Microsoft will also offer access via the cloud. In fact, following up on its purchase of Gaikai, Sony plans to offer a range of gaming from the cloud to multiple platforms. This may include older titles that it cannot support on the PlayStation 4 due to a lack of native backward compatibility. If such capability is expected to work, why bother to have hard drives in these consoles at all? Indeed, hardware makers of many stripes are starting to ask that question."
