Probably the same fate as the last one. Used on XV and maybe anything following that up, then retired.Yeah I thought they just said FFXV is almost completely running on Luminous already...
EDIT: Though if they STILL have serious trouble making that engine that really raises questions on SE's ability to provide themselves with an engine. Last gen was a pain in the ass with the Cell processor and the fact SE was casting their lot (initially) with the PS3 first and foremost, but now it's more standardized across multiple platforms... what the hell? They probably should just be getting 3rd party engines, though I guess UE3 burned them some.
