It looks like the rumors that were going around a few weeks ago were right, as Sony have just acquired cloud-based gaming firm Gaikai for $380 million. The news is very new, so there's not much meat here.
Gaikai is a California-based company, and until now, the company had only raised $45 million in funding. So this acquisition could be a knee-jerk reaction to NVIDIA's cloud-based future of gaming with GeForce Grid, or the future of gaming in general. More as it comes.
