The only technical information that is available is with Konami, Hideo Kojima, Kojima Productions and any presentation including this one that they may make.
That said there are game developers that are known for trying to use the hardware to the "best of their abilities at the time" of them developing the game engine for the game genre and the type of game that they are making, often alot of people will miss that and lots of things get lost in translation from the Japanese language but that is roughly as I understand it.
These game developers who like to ignore easy to use programming language tools usually are composed of seriously technical guys that are willing to break their fingers writting code and so on after spending months studying the hardware.
This does not mean that they are better than other game developers its just that they are different, however they eventually are able to make a more proper and accurate claim to using XX% of said console hardware.
In the case of the Prototype PS3, Hideo Kojima's team was asked what can they do to make their next planned MGS game, that is no different then when his team was asked the same thing back when PS2 was going to be released, however the main difference is that the evalutation hardware had generous ammounts of ram and bandwith that would not be affordable in the final retail hardware as planned unless Sony was willing to charge more money for the console and given the PS3's history as we know it, we are well aware of all of the complaints some gamers made about the price even though they are ignorant of how much technology really costs, the man power, the hours, etc. Its a very complacent generation of gamers.
You could only expect such a machine to have a 8800 prototype if you (and no I don't mean you) live in a world where the laws of reality are violated.
I have been thinking about this for a long time now and I have plans of making a thread about it, based on my limited but very nerdy knowledge and the short of it is that for you to expect anything like a retail PS3 with 512XDR, 512MB GDDR and preferably a 9800 GPU would have to be when the GPU could be made using a 55nm engineering process at Sony's fabs (who make RSX)
Therefore that would make releasing the console in the year 2008, where because of that Sony would have no choice but to use a 45nm Cell (because IBM reached 45nm in 2008) and the console would reflectively cost slightly more than the PS3 we knew that launched in our reality.
Then you have Nintendo with a king of the hill empire and an unchallenged XBox 360 roaming free for nearly three years, just racking up people who did not want to wait or eventually became shocked at the price once it was announced.
The things then to speculate is would people respond positively or take a wait and see luke warm attitude with such a PS3 given its higher spec, higher price and first gen game that would not look as polished or all that different than third generation XBox 360 games, and titles like MGS4 would end up with a 09 or 2010 release because after all you cannot realistically expect to make the console more complex and fast and be easily tamed in a short time.
