What's this about demos? The entire article was based on Sony's financials, not about the quality of the upcoming games.
There is some truth in what this IGN guy has written. 1.65% is a thin margin between a profit and a loss since Sony isn't just a consumer electronics company (film, music, television, etc.). That figure is the overall margin for the entire company including all groups. Consider that conglomerate competitors of Sony such as Apple and Microsoft posted margins of 9.97% and 31.59% respectively.
Still, I wouldn't worry about Sony all that much. In April of 2005 (their fiscal year ends in March) they posted an 85% profit increase over the previous fiscal year despite posting an approximate $530 million loss for the 4th Quarter. I believe they were still able to meet their payroll obligations.
The thing to look out for are the cash reserves for Sony. Though their revenues are always large enough to offset some losses from their various groups, the truth is as a corporation, Sony only possesses $5 billion in cash. That's almost 7 times less than Microsoft and this is why Microsoft has been able to stay in the game since the Xbox division has yet to turn a profit.
Microsoft's own worries will be growing as well with the delay (and poor reviews thus far) of their new operating system, Windows Vista and growing concerns over Google's expansion.
To conclude, Sony is not really in trouble, but to outperform the market expectations, they ought to act like they are. The PlayStation will continue to give them a nice cash cow, and really, Sony's already warned their investors about the initial costs and profit losses that will occur. If Sony can get the promised 6 million unit install base of the PS3 set by end of fiscal year (March 07), then everybody will relax. Despite the price points, if Sony ships 6 million units, I think 6 million will be sold.
Overall, Gerry Block's article is rather complimentary of Sony and seems optimistic about its future. Don't know why everybody got so irritated by it.
