There isn't enough information to give a good answer.

yes I know I used the wrong word.

I have no idea.

Well at CES they mentioned that the average monthly data throughput for PSN was 25 Petabytes, or around 800 Terabytes a day. That sort of bandwidth doesn't come cheap, around 9Gbps (roughly a OC-192 connection, typically costing around $US1 million a month). Plus storage costs, support, power usage, etc. It would add up, how much to I'd only be guessing though.

My theory is, PSN costs Sony money, which is why they are pushing for it to extend to other Sony devices now. More devices means more bandwidth sure, but storage costs always get cheaper with time, and people buying video's from PSN on their Bravia's will be paying money, unlike current PSN users who would download a lot of free demo's and trailers, which cost Sony to host and transmit down the tubes without any monetary reward.

Sony at CES basically said that PSN was one of Sony's core integrators for their product lines leading into the future, and it seems Sony is committed to it.

8 million. That's my best guess.

Well, PSN doesn't cost Sony anything because it's making them profit.. That would be like asking how much a PS2 costs Sony.... But, if you're looking for an answer before gains, I'm not really sure. I heard somewhere on this site they get 16 cents of each gigabyte sold.

People are paying for PSN (or at least I am). I've bought several games, and a couple movies from PSN. I'm sure that contributes to why PSN is free. Because people are paying for it. But, only for what they want.

The only thing i know that it was expected to make half a Billion (500 million) dollars

by the end of 2009 (300% year-on-year increase).
