The problem with this kind of report is that preupgrade uses the live
repositories, so any kind of package dependency-type issue you hit is
more to do with good old packaging human error than it is with
preupgrade, and is not necessarily likely to be encountered by anyone
else, at least in precisely the same way, because the repos change all
the time. You'd be about as likely to hit trouble with any 'live repo'
upgrade in this case (yum or DVD/netinst with remote repos enabled).

anaconda does something like --skip-broken - possibly more powerful - in
the interest of making sure upgrades at least go through, so in some
cases where yum would just refuse to run, anaconda will force an upgrade
through and leave a somewhat-problematic dependency state until you fix
things up.

preupgrade uses the 'release' repo, it doesn't include updates-testing,
so it's normal that after a preupgrade, if you enable updates-testing
(which is default for pre-releases), you'll find a lot more updates
available.
