s'kay, just a little chiding. As far as I'm aware, the current theories are...
=Final Fantasy VII: The Last Remnant (Basically, theorized as Dirge of Cerberus 2)
=Kingdom Hearts: The Last Remnant (KH Gaiden, placed in the past to explain Xenahort's... however you spell it, Zeanooto, whatever... past. Basically, that ending CG)
=Final Fantasy XII-2: The Last Remnant (Yet another FFXII spin off on the DS/Wii. Unfortunately, this theory was born from people who can't read Japanese, reading Japanese... so no)
=Final Fantasy XIII: The Last Remnant (Yet another spin off from FFXIII, simple, but I doubt it since all the other subtitles are in Latin and I doubt S-E would announce more games till they got a measure of FFXIII's financial success)
=Something else (Something else

)
