Sony playstation division only makes up about 10% of Sony's overall revenues (7.2 billion out of 68 billion) so it doesn't make much sense that an announcement from just one of their competitors would have such a large impact on Sony's total valuation.

That was super hard (typing 'Sony' into Google News). If you're looking at stock prices by yourself and trying to draw your own conclusions you'll probably end up looking like an idiot.
