It’s officially happened. Classic and Kubrick have been removed from WordPress as per ticket 10654. We all know by now that WordPress 3.0 will ship with Twenty Ten which is the new default theme. Those who are upgrading WordPress either manually or automatically will receive Classic, WordPress Default and TwentyTen. Those who install WordPress 3.0 as a new install will only receive Twenty Ten. Those who use Subversion though will see both classic and kubrick be removed the next time they update.
The goal is to try and get everyone who is running either Classic or Default to upgrade their themes to use the ones located on the theme repository as 3.1 may be the version where these two themes disappear for good. Is it a sad day or a celebration?
