Intel will not pull functional 3.0 (let's not even imagine 4.4) drivers out of their magic hat, but Intel integrated GPUs are the main GPU in every El Cheapo computer, and in the major share of non-tablet computers anyway, too. And, outside the world of Android, they're pretty much omni-present in tablets as well.
Which will probably mean no more and no less than OpenGL will simply not be supported (or supported even worse as it is now) on a considerable share of hardware. Sorry for being pessimistic, but I just can't see Intel producing a quality 4.x driver and undergo certification any time soon. They'll just show everyone the middle finger, knowing their CPUs are sold anyway.
I would be surprised if they added this certification if Intel haven't already said yes to it. What would be the point if it's still just AMD/Nvidia?
I really don't consider Intel to be that big of any issue. Their integrated graphics are in a completely different class compared to AMD and Nvidia's dedicated GPUs. I mean whats the real advantage to being able to enable the latest OpenGL 4 / DX11 level features in a game if its going to run at 5fps?
That seems rather irrelevant in the context of conformance, where the point is that any features should behave the same, which is just as important if one only uses 2.0 functionality. AMD/Nvidia are already close enough, and the real advantage of the conformance tests would be when writing an application that doesn't require the beefiest hardware and being able to rely on it working the intended way on any device.
