outdated text about 64bit
On the download pages with still display:

64 bit version
Download the 64 bit version if you use a modern computer and want to benefit of your modern hardware.
This seems to suggest that there would be either a common choice between 32 and 64, or even almost that the 64 would be the 'specialty'. It seems to make more sense to offer 64bit as the default without any additional comment or just have a note that for old hardware an alternative 32bit install still exists (which is xfce minimal only).
