Looking at the TOC for the Camel, I think most of the hard work is done. By the time Larry does Apocalypse 8 ( references ), most of the language design will be done and work can begin in earnest on actually coding the language.
Of course, Apocalypse 7 ( Formats ) should be very short -- something along the lines of "They're dead, Jim".
So, we have 2 more hard ones to go. Figure 6 months for those. Frankly, I would guess they are gonna work real hard to get it ready for the Perl Conference in 2003, but I don't know the date of it. So, I will guess 2003-08-15
