i honestly don't think a sequel would go over well... FF IX was a hodgepodge tribute to Final Fantasy 1-6 and kept that medieval aesthetic and all it's trappings... if they were to do a sequel i'd expect it to be a tribute to Final Fantasy 7-15(minus 9)... considering the amount of hate those get from the FFIX fans and jaded old-school purists alike, i don't think the original FFIX fans would like it at all, except for maybe a few exceptions... i would rather they do a remaster or remake and fix all the problems that make FFIX a mess, like useless Trance, unnecessary Magic Stones, and horrid battle load times...
