I raised the same question a couple of months ago, just to get a discussion going on what we consider "deprecated". Python 2.5 is one of those versions that actually work pretty well, so it will probably be here for a long time. A perhaps better way of looking at this is how many packages that depend explicitly on 2.5 to work and understand why upstream stays there.

For me as a fellow package bumper, I'd say that 2.5 is still good to go.
