ok nowwww i think i understand. so a game written in GL would translate to GL ES, but only for the limited feature set that GL ES offers. everything else would need to be rewritten.

And in fact you could already do this by limiting yourself to the common subset of functionality and #ifdef'ing the rest of parts, which any sane application was already doing probably as those parts are quite machine dependent.

So, as I was saying, this will have little impact.

So will this make it easier to, say, port an open gl PSX GPU plugin to open gles 2.0?

I guess you meant an "existing" PSX GPU plugin. The answer is no.

Just steal and/or enhance COGL from the Clutter project. I think the bottom of this link says it all:

COGL is a low level OpenGL abstraction library developed for (and part of) Clutter. It is used primarily by Clutter to provide a common rendering API that works transparently across OpenGL >=1.4, OpenGL ES 1.1 and OpenGL ES 2.0.
Some more info here.

Oh, and it's already in Maemo 5 and MeeGo.

Nope.

This means exactly the opposite.
If you are writing software using OpenGL ES 2.0 you may now run it on any OpenGL 4.1 compatible device without modifications.

OpenGL ES is a subset of OpenGL, so if you use any features specific to OpenGL the code won't run on OpenGL ES compatible device.
This announcement means that all OpenGL ES 2.0 specific features was accommodated to OpenGL 4.1.

Thanks to all those with more knowledge than me for providing clarification. This is directly from their press release

New functionality in the core OpenGL 4.1 specification includes:

* Full compatibility with OpenGL ES 2.0 APIs for easier porting between mobile and desktop platforms;

So why would they do this? Who wants to run mobile apps on their desktop? Maybe I'm just being thick and missing the benefit of this.. wouldn't be the first time
