Big Nerd Ranch hints at Panther ship date?

MacNN: “The Big Nerd Ranch
will launch its revised Cocoa training class September 22-26, which has
been modified to incorporate new features being added to the Panther
release of the Mac OS X operating system and developer tools.” Unless
all the participants are required to sign an NDA, does that mean Panther
will be out by then? The quote on the Big Nerd Ranch site says this,
however: “Why would we teach students to use Project Builder just weeks
before it is discontinued?” I’m not sure what to make of it.
