Breaking news: Sony has just acquired the videogame streaming service Gaikai, according to Venture Beat. The link was just forwarded by Gaikai CEO David Perry himself, who had previously founded Shiny Entertainment (Earthworm Jim, MDK, Sacrifice). The big question is how this acquisition might affect Sony's plans for the next PlayStation. More as this story develops.
EDIT Here is the official press release from Sony Comnputer Entertainment, verifying that it is actually the PlayStation business making the acquisition, not Sony Corp. as a whole. The press release reads that "through the acquisition, SCE will establish a new cloud service, ensuring that it continues to provide users with truly innovative and immersive interactive entertainment experiences."
