The lights are on
So that is pretty much the question. I remember seeing a Sephiroth costume for Sackboy when the game was first launching. Its been awhile and I still haven't seen anything. Does anyone maybe know about it?
I just remembered this at well. They showed a sephiroth sackboy (and a solid snake one) at the 2008 TGS if I remember right. I wouldn't expect anything more than a costume pack to come out, but it's pretty odd that there hasn't been one yet.

They've released a few costumes for a single character from a series (i.e: Altair costume, Kratos costume, Chimera costume, etc.) and haven't released any others. I'm not surprised if they don't release anything else regarding FF seeing as they're really slowing down on content after the holiday. Sephiroth costume is probably all we'll get.
