Last I heard they were talking about splitting divisions into entertainment and electronics.
World Wide sales of PS3 were 77 Billion, 360 was 76 Billion. I don't see PS4 taking a big hit anywhere.

Your numbers are ludicrously off if you're talking about units shipped/sold. You're saying that everybody on the planet has bought at least 10 PS3s and 10 Xbox 360s. If you mean revenue from system sales in USD, that's still ridiculous. Assuming $300 per system, you're saying there are about 250 million units sold. 77 and 76 million units sold seems more correct.
