The Wanderer of Time
FFX has never had more attention than VI, given that roughly 40% of the FF fandom loudly declares it to be the best of the bunch (the other 60% says VII or any of the others).
You also seem to forget that the PS3 is newer than the PS2...
Also, I'd say PSOne, GBA, Wii, and PSN isn't exactly OVERLOOKING anything.
PS1, Wii and PSN don't count, they're just the same basic game, no one cares because you've already played it. And while FFX has less attention from the fans, it has more attention from SE. It's had a sequel, it and the sequel both had a "Final Mix" type re-release, and now it's getting a PS3 remake.
