This board is very much to get hardware into the hands of developers who are porting software (such as me), it's not really something for end users at this time.
Sony used to price Playstation 2 dev kits at $thousands. I always figured that pricing was to ensure only rich companies with e.g. marketing budgets were going to develop games.
It's a bit bizarre that people are expecting RaspPi prices this.
What started as an "educational" board has pretty much turned into a turnkey cheap Linux board for a lot of people. So they expect that out of every board now.
I also wish Broadcom hadn't dumped these things under market price. That's another thing that has really messed up expectations.
So there are reasons why this hardware was expensive. And there absolutely no reason for console vendors to sell them at loss simply because otherwise companies will buy more devices than absolutely needed to get job done.
As for the limiting access to console Sony and others managed it fine without making devkits pricey.
You might be thinking of the alpha dev kits. Those were basically gigantic metal wirewraps, and if you were at a large game dev you might get one or two locked away in a conference room. I can't remember off hand if those cost anything actually? You had to be a substantial game studio to get one in the first place, and Sony took them back.
Either way, that's not what I was thinking of. The production PS2 dev kits (called "TOOL") cost $thousands and were not manually constructed. A game team would have a lot of these. I can't imagine these cost as much to build as they charged, especially years after the PS2 launched.[1]
[1] - I wish I could remember/find the price for the TOOL, I want to say it was like $10 or $20K, even 2-3 years after PS2 launched?
