I apologize for being vague in my question.. I know about Long's Peak, but it was supposed to be out last month. Just curious what's happening. Waiting eagerly.

There was never a fixed date for GL3.0's release; they had hoped to get it out last year however as they found some unresolved issues they wanted to fix.

This update is the foundation for at least 2 more updates (Longs Peak Reloaded and Mt. Evans) and probably many years going forward so they aren't in a rush to get it done and leave flaws in it.

OpenGL.org thread on the subject.

It sucks a bit to say but this shift was quite a stab for me.
IMHO they should never have announced (not even unofficially, let alone at siggraph) it only to take this pill.
What worries me is back compatibility. We all know GL3 should run on old HW as well and it basically lays down foundation for GL4 paradigms delivering more performance.
Historically however old HW which had greater benefit were the first in being discarded from driver development.
Considering how DX10 HW sales are going I fear this may be a huge error for GL3 popularity - I just hope vendors don't go much for the marketing this time.

The other thing I fear decisive is MS's position on the new API. I generally believe competition is the best way to show "their API is better" but I hardly believe they'll take this route.

GL3 will have a min hardware spec due to some of the base requirements, I believe you'll be looking at a min of a R300(aka ATI9x00 series) or GFFX due to the requirement for Floating point textures and lack of fixed function pipeline; yes it's all shaders from here on out.

However, given that the R300 series is a good 6 years old this really isn't a problem 'old hardware' wise; anything older or less able hasn't had a true driver update in sometime anyways.

Also, it's not like GL2.x/1.x is going away; you'll still have access to it for older hardware if needs be.

The annoucement was a sane idea; people wanted to know what was going on. However where they have gone wrong is not keeping us in the loop. It took alot of almost begging to get that information out of them and while many agree with their choice to get it right for future updates (GL3.x, not mention of GL4 yet) it would have been nice to have been kept more informed.

Yes, that would be just fine - even dropping FX would be ok-ish.

Sure, but without performance improvement although I recognize it isn't a great issue.

I agree completely. I suppose everything would have gone better if they given updates more often.
