[quote name='Caliburn']FES might kill its value, or it might retain the value; this is one game that's hard to gauge due to the rumor of FES. I doubt the premium goods will be the same, and people might want this still... Valkyrie Profile: Lenneth PSP didn't affect Valkyrie Profile PS1 much.[/quote]
It looks like FES is likely coming stateside. In addition to all the previously existing rumors and the fact that one of the voice actors let it slip that he'd been contracted to do voice work for FES, EGM (who has a respectable rumormill, IMHO) is now saying its looking like its heading our way.
The question is, will it be an add-on disc (which requires the original disc to play, thus will not kill the value, only increase it)
...
or will be an independant booting expansion? (In which case, yes, it will kill the value)
Either way, i'll be preordering this baby.
BTW, it is in my opinion that the reason Lenneth didn't kill the value of Valkyrie Profile much was because it was a somewhat shoddy port in that in-game load times were worse, menu access has a load time, there is slowdown/stuttering in-game, the stretch aspect ratio cause some of the low-res sprites to appear blurry, and its based off the original Japanese version of the game which is inferior to the U.S. version.
So in that respect, I don't think its really a true comparison between how Lenneth affected Valkyrie Profile and how FES will affect Persona 3.
