that it seems Sony claims "OpenGL ES 2.0" support for Playstation3. so, i guess they do the same, i.e. read "OpenGLES 1.0 + some GLES 2.0 " what is actually the case as you said, as "OpenGL ES 2.0 support", when technically there is no full ES 2.0 support. also, in another link that i lost, i read that graphic libraries that Sony developed for OpenGL support on Playstation3 use not only the RSX (nVidia graphic chip), but also the "Synergistic Processing Elements (SPE)" in the CellBE CPU - that i guess adds even more features compared to using just the graphic RSX processor, because SPE are 7-cores in CellBE CPU and very fast, i.e. like software emulation of graphic features.
