Hi Doom Lord,
I'm completely unconvinced of your standards argument. Guidelines yes, standards no.
The whole advantage of S-3D gaming is you can do it today. Even with the biggest names behind it, it is only now starting to get the attention it deserves (though not by the companies who direly need the gamers to buy their products, it seems!). Just because you have the means to program something a certain way doesn't mean the motivation is there to create the content.
If I were an outsider looking in, and I had to choose between having a standard DirectX API for S-3D which nobody cared about, and having 10,000 MTBS members talking about 3D amongst themselves and their friends, I'd go with the 10,000. Standards have no marketing benefit whatsoever in the gaming world.
Look at DirectX 10! It's a "standard" API. Microsoft has backed it with all its might since the beginning. Are 100% of the games released today written in DX10 with the full DX10 applet being used? By the time DX11 is released, will this be the case? I'd have to say no to both questions.
Demand first, motivation first...standards - if relevant - later.
Firstly i'll just state that this is my "opinion" and I don't work in the gamming industry then that is all it reallys is
Any way with reference to you post about DX10 - although you may not be using DX10 yet you are still using the DX standard as a whole just the not the latest implementation. So I still go with needing a standard.
However I do agree with you in that there has to be demand first but not all demand comes from the consumer. A lot has to do a good product and even better marketing.
