The source in the OP covers the losses of the PS3.  Here is an additional one showing losses of almost $2.5 billion just over a year ago:

As I stated in the post you quoted, actual development/marketing costs of Blu-Ray are Blu-Ray consortium secrets, and arn't as easy to assertain from company reports as the PS3's losses, as Blu-Ray doesn't fall under an outlying division like the game division.  But I will show how you're own post proves my point:

Noone wants to be forced into buying an entirely new medium.  Studios are wary of supporting a new medium.  The public only want ONE medium.  With that in mind, ignoring the massive costs of actually developing a new technology like this, do you have any idea how massive an investment was required of Sony and it's partners to market, distribute and subsidize Blu-Ray against HD DVD, not to mention paying studios for loyalty.

To put beyond doubt the likelihood that Sony has spent FAR more than a billion dollars on Blu-Ray, see the link below.  Sony spend over HALF A BILLION DOLLARS just to bring ONE studio permanantly into Blu-Ray's exclusivity portfolio.

As for Microsofts losses on the 360, theres a very convenient table floating around VGC with a quarter by quarter, year by year breakdown.  Failing that, you can simply visit Microsoft's website and get their financial results.

In future, if you're going to make ridiculous, unsubstantiated claims such as your $7 billion on the 360 alone post, it would be inadvisable to then accuse OTHERS of insufficient referencing later on in the SAME thread.

There's a phrase your provided article you should read, "predicted loss" those aren't official numbers, and those "predicted" numbers are lower than what you claimed earlier.

With your blu-ray arguement you have now expanded into the marketing and gaining of support for blu-ray to back up your "1 billion cost" claim. I have been referring to the actual cost to develope the technology, not to market it. Again, Sony "paying" for loyalty of a studio isn't part of the cost to create blu-ray.

I'm sure someone of your intelligence would recognize that looking at MS financial statements won't help you find out it's losses on the 360 either, as MS has clever included several other products into the same division.

You're quite funny starcraft, I made one claim, not even a claim, and you try to criticize me, while you have made several claims, and when asked for a source you refer to someone else's OPINION.

If you want to pull off this whole "I'm smart and mature and us common sense" you might want to handle yourself better, especially your sources of information.

 No. The PS3 IS a failure. A fantastic failure. 3 billion in the hole and they don't really have much to show for it. Actually I would put the price of that failure at between 5-7 billion dollars. Thats the difference between a successful PS3 and an unsuccessful PS3. Thats the opportunity cost factored in as well. Face it, it was a terrible design, they screwed up worse than Microsoft did! 70% market share - 23%, Billions in profit - Billions in losses.

Nintendo >>>>>>>>>> Microsoft >>>>> Sony as far as intelligent business decisions go.

Blu laser disk development was from very early developed and sold as profesional data archiving systems many years before the existing blu-ray movie stamping process existed.
The mass effect of the market demand for blu-ray drive mechanisims by sony, samsung, panasonic, sanyo , sharp ,apple , dell etc is driving the cost of the blu-ray drive down to littel more than a standard DVD/CD only drive.
Agree with the last post - Sony are probably making profit on hardware already.

Approx 50million PS3 Blu-ray games disks have been sold, this is more than double the number of blu-ray movies sold !

No need to cut the price of the PS3 it is selling heaps every week. Last week it sold like 320k. PS3 will outsell the 360 worldwide no matter what the 360 does. PS3 price will not be cut in the future unless the 360 beats the PS3 in weekly console sales.

Its actually worse than that ... The PS3 put the division $3 Billion and was one of the major factors to (dramatically) lowering the profitability of the Division for the two years leading up to its launch; that should work out to being close to a $5 Billion expense, and if the product was successful they should be able to make a couple billion dollars and fund the research and development of their follow up console.

So long as the PS3 outsells the XBox 360 in total console sales LTD. Beating the 360 in total market share is all that matters to the PS3. 5.5 million gap and closing. the Nintendo Wii is out of reach. The Wii is 14 million ahead of the PS3 and margin is growing.

 Damn, you're right... it depends how far forward you project the losses and if you factor in "good will" as a cost as well.

 so, $5 billion now? + another $5 billion easily that they could have earnt then this whole fiasco could have cost them a cool $10,000,000,000 - factoring in goodwill, profit/sales forgone, etc. Oh yea they also sold off their fabs as well.. probably to improve their cash position I bet.

I think there are some very nervious people in SCE headquarters...

It will be quite hillarious if the 360 gets a price drop soon and spanks the PS3 for the rest of the year. It'll be even funnier if they maintain profitibility whilst doing so.

That will never happen. The PS3 has continuously outsold the 360 in weekly console sales since December 2007. Over 30 straight wins- PS3 over the 360 and counting.

360 will never outsell the PS3 in weekly console sales.
