Updating to the OpenGL3 spec

I was just curious as to if Irrlicht will be updated to adhere with the OGL3 specification. For example, the immediate mode drawing in draw2DImage, and all the other deprecated functions.

They are deprecated, but not forbidden

Anyway, once we have ogl-es support, there will be OpenGL drivers which will already adhere to OGL3 for about 95%, so taking those and make a pure OGL3 driver from them won't be much of a problem. Though you won't get much benefits from it, until let's say 2012, when optimized drivers will be available which will give some speedup with optimized OGL3 hardware...

This might be hearsay, but I heard that OpenGL 3 spec was optimized for CAD, not game devs

Tis true, I think one of the only good things that came out of it is GL_EXT_direct_state_access. It allows you to directly set states without alot of popping/pushing etc. Would be great if Irrlicht can be re-written to use this.

If irrlicht where to be updated to GL3, would it be selected as OpenGL, or OpenGL 3 upon initiation?

IE, an extra driver mode

Either extra driver, or compile time choice with ifdef's. However, a separate driver shouldn't be too much of a problem, so we'd have another option on startup.
