Sample code posted at the ADC could prove that preview versions of Mac OS X 10.5 Leopard might be unleashed to WWDC attendees next week. The page has since been taken down, but DuggMirror retained a copy for our speculating eyes.
The piece of sample code is QTNoStepsDemo, a meaningless chunk of code to us non-developers, but one aspect of the page (posted on Apple's site 8/01/2006) is what raised the flag: the code's build requirements specify "Leopard Preview". If this page is legit, it certainly isn't a blatant statement from Apple that Leopard will indeed be unleashed to our developer overlords, but it definitely is suspect. As with all other tidbits we've been uncovering over the past few weeks, we'll just have to stay tuned for Monday's events to see what Apple's engineers have up their sleeves.
