It depends on the prerelease and who is running that product's
development.
I can proudly say that I was on the CS4 Master Collection prerelease
now. In fact, I think the NDA allowed me to say I was on the CS4 MC
prerelease even while it was still in development, however, there were
certain things I could not discuss. Adobe was great about telling us
what/when we could discuss and it usually mimicked what Adobe folk had
previously previewed at user groups or other media.
Since we have not heard much about CF9, my guess is that the CF9
prerelease is a bit more tight-lipped.

Where...I even double checked it and didn't see anything the last time
we had this discussion/comic dialogue...
