Running preupgrade on F9 doesn't see F10 as an option

[Claude Jones]

On this F9 box, running the preupgrade-0.9.3-3.fc9.noarch version 
of preupgrade, I get the GUI but there are no upgrade options 
offered for F10; ticking the "Display unstable..." box gives me 
the option of upgrading to Rawhide, but still no F10 -

Ideas?
