For all we know, this sort of thing might get leaked intentionally as a middle ground between between annoucing it and keeping it a secret. The most interested and active users will know about leaked information, and they can put off buying decisions and have greater long term satisfaction. If you bought a machine and 2 months later, exactly what you wanted two months ago comes out, you probably won't enjoy that experience very much. However, less discriminating users probably both won't know about the leak, and won't find certain things coming out quite as disappointing. I think it probably works out decently for Apple even if they really don't want the leaks, much the way piracy probably helped Microsoft Windows by helping make it a complete de-factor standard (though Microsoft seemed aware of that and seemed not to crack down as hard as they might for that reason.)
