I found out today that with the release of Sarge on the horizon, the next Debian/testing name has been selected. With buzz, rex, bo, hamm, slink, potato, woody and sarge having been used already, the release managers have settled on "etch."
For those that haven't caught on, all the codenames are taken from the Toy Story movies.
Debian has three streams (well, it actually has four, with the last being 'experimental' but I don't know that anyone really uses that). They are stable, testing and unstable.
Packages go into unstable, then after two weeks (and no hassles) they move into testing. Every 18 months or so, the current testing gets frozen, and that gets moved to stable, and we start with a new testing. This process is called a release.
Stable is what's known as the release, and we currently have woody as stable. This means that no new packages to into woody, with the exception of security fixes. This is what you run on servers.
Testing is what most people use on their desktops, unless they need the bleeding edge-ness of unstable. Testing at the moment is sarge.
Unstable is never released as such. Unstable is called sid, who if you remember was the boy next door that used to break toys for fun. I thought it was humerous.

In response to Hale's question regarding the release schedule, it looks like September 15th will be the release date for Sarge, of the release-critical bug count gets down in time.
