Read the whole thing. Was a pretty decent read, learnt a lot of stuff I didn't know (particularly about that engineers vs. executives stuff, which made me both pleased and sad at the same time).
Anyway, I had a couple of issues with stuff from the article. The first (and easiest to explain) was "Sony plan on selling the Vita at a loss for 3 years", then linking to a neogaf thread which itself links to an examiner article. Kaz's quote is translated from Japanese and tbh I think it's too ambiguous to be used for any kind of evidence until he re-iterates. I see it as "The Vita project will be profitable in 3 years", meaning all the costs to do with it (R&D, marketing, production, perhaps some very early loss leading) will be recovered in 3 years. Other people (including the author of this article) read it as "Vita will be sold at a loss for 3 years before it becomes profitable". With the way Sony have stubbornly refused to drop Vita's price, I think this is wrong, but without any kind of clarification we're not going to know for sure either way. Which is why I don't think it's a very good point to make.
Also, market cap. No make no mistake - I realise Sony's market cap has bombed since 2000 and is continuing to fall, but part of that is a result of heavily, heavily inflated share prices during early 2000's. Microsoft's cap is less than half of the $618 billion it was in 1999, for example. And just to throw in the other of the big three: Nintendo's market cap peaked at an extremely high $85 billion in 2007 yet is worth $14.8 billion today. I know, I know, it's worse for Sony because they're a much bigger company than Nintendo, but still.
In any case, thanks for linking :P I don't particularly like reading doom articles about Sony but sometimes you have to be realistic and realise things aren't great. I'm still going to be hopeful that Kaz can turn things around, and at the very least that I can get a few more great years of Playstation products.
