Hmmm...
I believe some of the most important tidbits have been that this product a) took several truck loads of time to develop, b) goes right to the heart of 3e, but will not be quite apparent at first, c) required a bucket load of stat block and d) is really cool, but will have to be seen first-hand to appreciate the full 20d6 of coolness.
Now, I do not profess to be a master of this reasoning-out business (yet, muahahaha...?), but I will start with a thought or two that I may add to later.
I think the last point may be the most revealing in terms of trying to intuit the type of product this is going to be. However cool it may sound, or how well it was written, it can only be fully understood once you see it, so it must have some of physical presentation that goes beyond the standard of d20, whether it be cards, miniatures, a board game or something entirely different.
Another thing, which I don't quite remember the exact wording of, was whether it appealed to the core of 3e, the core or d20, or both... A few different interpretations of this could apply. One, if it is the core of d20, it may have to do with the system of resolution, or the way statistics are treated, or some other such rules based application. If it is the core of 3e, that could of been meant as the core of d20, or it could be viewed as the core goals behind the creation of 3e and the new edition of D&D...
Uh... give me some more time to think... God knows Monte has taken his sweet allocation of it!

Small side note: Let me know if my rambling seems to you to be:
a) reduntant
b) stupid
c) brilliant ( please vote for this one

)
d) useful
e) mediocre
Just a sort of gauge as to how I'm doing.
