Getting deeply into the mastery of speculation... sorry in advance if I am repeating what someone already told here!

I just did a more detailed research on bugs.maemo.org for all bugs marked as FIXED with the Target Milestone as "5.0+", and the latest build mentioned was always 10.2010.08-XX (08 means the week and XX is the version of the build for those who don't know):

Qt 4.6.2 for Maemo got its public release at 15th Feb (week 07). Source: http://labs.trolltech.com/blogs/2010...mo-5-released/

I am pretty sure the PR1.2 will be based on a version 10.2010.08-XX, since it was the build with the most number of builds I've found, being the latest build 10.2010.08-23 the latest (Source: https://bugs.maemo.org/show_bug.cgi?id=9182). 23 builds within one week doesn't seem feasible...

Anyway, week 08 was between 21 and 27st Feb... @casper27 mentioned in a previous post on this thread that last FW update took 5 weeks between the build and its release. Sure this may vary depending on how the tests go, but the bug 9182 was marked as RESOLVED/FIXED at 5th March (build 10.2010.08-23 ), last Friday... so I guess they are still including bug fixes to PR1.2.
