If I look back at the archives for Aug-Oct 1999, the numerical tidbits had to do with spell durations (because of going from a 1-min round to a 6-sec round), the concept of critical "threat ranges" (a new thing for D&D), armor class (different numbering system), an incorrect/speculative chart showing ability score modifiers, an official preview of two new "stats" for armor (max dex and skill check penalty).
Yup. For the same period, I think we've gotten similar amounts of information. We know to look to Saga for static defenses/saves, we know spell levels equal character levels, we know pretty much that crits don't require a confirm and have effects, we know that all classes will have at will/per encounter/per day abilities, we know races have traits similar to class abilities which increase as you gain levels (and some of the names of these traits), we know CR has been replaced with static XP awards, and that adding these up creates an encounter, we kow about wizardly implements, we know magic item creation does not require XP, we have some names of wizard attack abilities, warlord buff abilities, we know about monster roles, we know about new definitions of demons and deveils, we know loads about the default cosmology, we know action points are core, we know certain abilities are accessed at different levels of HP loss, we know saves vs. massive damage cause day-long negative effects but not death, we kow you can fall on someone to cause damage, we know the full atatck option is gone, we know social encounters require multiple skill checks of varous kinds, we know certain skill types such as spot and listen are now static scores to be beaten, we know tons of info about the D&D Insider tools...
And I've only scaratched the surface. Much more, and WotC may as well just send everyone a free PHB!
4E isn't different enough to 3E that they need to say so much specifically - yeah, they could post something about how a skill DC works, and we'll all say "yeah... we knew that"; or tell us what BAB is, or a million other things. But there's no point - the type of information available for 3E was different: the underlying structure was being changed and previewed; here, it's the same underlying structure.
People HAVE a massive preview of 4E - it's called 3E; or "the d20 system". There's only so much they can say without just handing out the game!
