My bad That's what I remembered reading in the past, but like I said I never programmed for the PS3.
At the start of the PS3's life time the fact a OGL|ES implementation existed was jumped on by the 'opengl everywhere!' gang and has since been reported as a fact the PS3 uses OpenGL... alas to this day the misinformation exists and thus this common mistake crops up
Yeah I still see that all of the time (especially on general gaming forums) and it drives me nuts. Hopefully the same thing doesn't happen to PS4.
