Arch and Manjaro have 32 bit options. Slackware 14.2 just released is available for 32 bit. Porteus has a fresh release pending for 32. The recent Fedora 24 has 32 bit iso. So it's not over yet. One snag however is hardware limitations on 32 bit machines. It may be possible to run a current browser on less than 2 gigs of RAM but I find it is not enjoyable. So it partly depends on what one wants to do iwth that golden oldie.
