Sony is not in trouble because of their stocks but because they are likely to report a 1.1 - 2.2 billion dollars loss in their next financial report, the yen is strong and Sony's products have a really low profit margin which is going to hurt them hard.
Sure, gamers are really narrow-minded when it comes to economics...
Edit: The next financial reports for the big three are going to look like that:
Sony: Sorry but we lost a billion dollars... yeah we've overestimated our profits for a decade now but hey... it can only get better!
Nintendo: Our profits have been hurt by the recession but we are still earning enough money to sell our next 5 consoles for a loss of 500$ per console. Each of our employees makes us about 100 quadrillion dollars a day, we think that's quite good.
Microsoft: Unfortunately the recession hurt our plans of buying the whole world. Instead we'll only buy Europe and Afrika this year.
Yeah that's over the top but you get it.
