Apple's a consistent company. Of course I know what WWDC is. Not sure if I appreciate your condescending attitude.
Obviously WWDC is going to focus heavily on Mountain Lion, as they announced Lion at last year's WWDC. Whether they announce they're releasing the Golden Master (or a stage less - or even higher?), it's still going to take another month or so before it's at a retail version.
I just think they would be making a lot more work for themselves if they released a new product now, before WWDC. If the new iMacs were ready now, you might as well announce them at the WWDC & get a lot more publicity from the announcement - weather you like it or not, the iMac is still a flagship product, and I doubt Apple will quietly update it without some sort of announcement.
You've lost your logical thinking with your own preconceived ideas.
Oh, and I know in the previous post I said ML will be released at WWDC - Sorry, in hindsight I should have said 'more information at least will be provided'.
