From the conclusion section of the Tom's Hardware article:
"We were expecting a lot from OpenGL 3, and as you can tell by reading this article, we’re disappointed—both in the API itself (with the disappearance of promised features) and in the way it’s been handled (a year-long delay and a lack of clear communication on the part of the Khronos group). With this version, OpenGL barely keeps up with Direct3D 10, and at a time when Microsoft has chosen to publicize the first details of version 11 of its own API."
