#7: Will the actual .spec files be released for GL3? Can we expect an xml-based format? (The .spec files are necessary for non-C OpenGL bindings)
#8: How will GL3 interact with the underlying platform (i.e. context creation)? Will WGL/GLX/AGL be extended for GL3 support? Will we still need the roundabout trip for multisampled visuals/pixel formats?
#9: Can GL2 contexts exist side-by-side with GL3? How about resource sharing? (IIRC this was mentioned at some point, but my gut feeling says this feature didn't make the cut - for good reasons, too.)
