Python plans for 12.04 LTS: Python 3.2 and 2.7 only. We dropped 3.1 in Oneiric and 2.6 in Precise. For 12.04 the goal is at least one desktop application destined for the default installation (i.e. CD images) to be ported to Python 3. Long term (14.04 LTS), we want Python 3.2 only on the CD, with 2.7 still available in main.
