The mozilla CD is going to be shipping shortly after 1.7 final is released. The previous CD had a branch nightly build from shortly before Firefox 0.8.
The question is whether to have 0.8 on this CD, or whether a Firefox 0.9 build (final or not) will be ready in time. Now that we're a couple of weeks on from that time, I think it's clear that 0.9 isn't going to be ready, so I guess the CD will ship with 0.8...
