It must be there but theres with dev preview ya never know if a bit could be missing but with final release its a no brainer

Maybe we'll have GL4 in 10.8 lol
I'd love them deliver OpenGL 3.3 given that it includes a few extensions that gaming vendors have been holding out for. What ever the case maybe I think that although the new version is great I'd like to see equal time optimising their implementation better so that not only do we end users have access to the latest OpenGL but it is optimised for performance as well.
I think I read somewhere that OpenGL Viewer needs to be updated to detect the new version.
If Apple says Lion supports OpenGL 3.2, I believe them.
I haven't seen the seed notes yet but like you said, maybe the OpenGL Viewer needs updating, either that, or the seed notes stated that OpenGL 3.2 was coming to Mac OS X Lion rather than pointing out that'll be in the Developer Preview build.
Gotta love that useless apple logo that doesn't do anything! And the awful huge Finder toolbar icons.
In fairness though, that was the style of the time, IIRC the PT Cruiser, transparency fad took off with every man and his dog jumping on the bandwagon. Even with the movement of the logo and so forth the pinstripe still remained along with many of the elements - but at that time it was cutting edge. I remember seeing Windows users lusting after it, wanting to find people who had ripped off the icons and trying to get their Windows theme to give them the 'Mac look and feel'.
It always brings back happy memories when I see screenshots like that - the good old days reminds me of my Amiga days before moving to the Mac:
Amazing how some whine about the 'grand unified menu' at the top given that pretty much all operating systems operated in that way, be it Atari, Amstrad, or Apple with Windows and CDE being the odd ones out - although IRIX with Indigo Desktop provided an interesting mixture of Amiga/Atari/Windows/Apple.
