http://wiki.lustre.org/index.php/Lustre_Release_Information reports that
2.0 is targeted for release in Q2 2010. :-)  And the movie "Lustre" got a
rating of 2.5/10 at IMDB.

https://wiki.hpdd.intel.com/display/PUB/Lustre+2.4+Scope+Statement has the
2.4 release schedule, and states (as was agreed by CDWG last year):

    Introduction

    Lustre feature releases follow a release train model, with feature
    releases targeted every 6 months. For the 2.4 release, the code freeze
    date has been shifted from a Dec 31, 2012 date to a January 31st, 2013
    date in a one-time date adjustment to shift away from freeze dates
    falling near the Holidays.


    Key Deliverables and Milestones

    Feature Freeze: 2013-01-31
    Code Freeze:  2013-03-31
    2.4 Release GA:  2013-04-30


The corresponding 2.5 scope page does not exist yet, since the features
for 2.5 are not yet finalized, but the 6-month schedule has been pretty
steady for the past 2-3 releases, and Peter and I put the release schedule
into every one of our LUG/SC presentations.

The planned dates for 2.5 are:

Feature Freeze: 2013-07-31
Code Freeze:  2013-09-30
2.5 Release GA:  2013-10-31


which are 6 months after the corresponding 2.4 dates.  I agree it makes
sense to have a single page which spells this out more clearly.

Cheers, Andreas
