Thinking it was was hysterical, he decided that, if they did add it in, he should add something from Fabula Nova Crystalis to cheer them on right back. Did I miss something more specific?

He did mention her by name, but I think exactly what he adds from the XIII series is still up for grabs. If I were him, I'd include a code in Lightning Returns to get a low-level replica of Lightning's sword for FFXIV. Who wouldn't want to have that hanging around as vanity/town gear just for kicks?
My understanding from reading the translation is that Lightning is being put in the game as a NPC. Of course, I might be completely wrong on this.
