I don't know if I agree with this. So in your opinion, we'll all go to macrumors one day and the top news story will be this:
"Apple quietly releases Leopard

Although no special event was planned and no release date was announced in advance, Apple has quietly updated their OS today to 10.5. The new OS is available for order online and in physical Apple Stores starting today. Industry experts everywhere that is, those who could be reached for comment on a Sunday are puzzled at Apple's choice for a quiet release of the much anticipated and most significant update to OS X in two years"
I don't care how behind they may or may not be on Leopard, there will be some event to show it off. As FF_productions mentioned, Steve promised special features. While Apple likes to give people little surprises, they're not going to make them go by the OS and try to figure out what all the new features are in Leopard, they're bound to announce them at some point, even if it's only shortly before Leopard is released. And it doesn't seem the kind of thing they would announce with just a press release, it will either be at some event where Steve or someone at Apple can show it off, whether specifically just for Leopard or as part of something else.
