Hmm, figures like loss of $37 "Per console" and the with no hardware revision I has gone down to "$18 per console" does beg the question of how much it actually cost "per console". I mean the console itself is mostly a pile of plastic, silicone and a trace amount of other metals, there is the time taken to make each one but that is mostly automated.
I think it is pretty poor economics to get too worked up about cost "per console" and seems to me like a fallacy.
I mean there are costs... and then there is revenue. You can't just divide the cost by the number of consoles to get the cost per console, it doesn't work like that.
What the "cost" is is buying or renting the machines that MANUFACTURE the PS3s and hire or employ the technical experts to get the job done. Then there is a labyrinth of other costs like warranty, legal, future R&D (playstation 4 won't come out of nowhere), distribution, PR, marketing, networking, production studios.
I think we should just forget about the idea of cost per console... it just has too many abstractions to have any relevance.
The only question that matters is "is Sony making enough money to cover their costs" and that comes from ALL sources, games and movie studios even. Because if they make a loss for too long and show no sign of ever making a profit, THAT is when we should care as that is the point either prices go up... or the company goes the way of Sega and their Dreamcast (not the case here) but that is the point where gamers should care.
We need to keep an eye on the general health of a company, not just obsess about the one aspect that we gamers are most interested in, the console, which is the most important, yes, but so many other invisible components are linked to that.
