The splitting of revenue/profit over divisions is a bit difficult to penetrate.
For fiscal year 07 the electronics division (that supply the games division with the parts necessary to build the PS3) had an operating profit of 356 billion yen, an increase of 121.8% over the previous year(!).
So while one Sony unit makes a loss from the PS3, another makes a profit. Unless you have better info than this (which is open to shareholders,) it is very hard to pin a number on PS3 costs up until now. And once you start to consider the intangibles of how much the PS3 helped their BR effort and what that will mean in royalties and associated sales of TV-sets, video players et cetera, even Sony internally will have difficulties making a solid assessment.
However, unlike Carl, I'd say that now that we have seen sales, and how their PS1, PS2 console dominance has been completely wiped out (along with associated software revenues), I would be very surprised if Sony in retrospect feels that the high cost of the PS3 was worth it. A cheaper, less ambitious console, released earlier may well have been a better play, that would have helped them maintain their console market position and as Shifty pointed out, allowed them to spend a LOT of money promoting BR directly.
You make some valid points, but still I do feel that Blu-Ray would have lost to HD-DVD if PS3 weren't able to launch with a Blu-Ray drive in it.
Using Blu-Ray in PS3 was the only way to make sure (and many people at Sony had the same idea obviously) that Blu-Ray had a good chance to beat HD-DVD in the shortest period of time possible.
