There was some discussion on the fedora-devel list about changing the default architecture for 32-bit Fedora. Which would mean that users running 32-bit Fedora with modern CPU’s will see some improvement, while older hardware will need to be supported by some secondary means or not at all.

There is a well written post about installer formats on the Acroread Unix blog. I recommend just reading over the post, even if you do not use Adobe software.
