I personally assumed that new content was being revealed first because it is of lower importance than the rest of the new stuff.  I expect each new revelation to be more impressive than the previous, or at least I'm hoping so.  I'd rather have new features that let the current figures pose better (as well as less set-up to the dynamics) than new figures to start over with.

So, they're going to tell us one new thing per week until release?  I didn't catch that they were scheduling it that way.
