I'm sorry but calling it next-gen is pretty hilarious since it's only made for 360 and ps3 in mind.
Next gen will be the consoles happening after these. Regardless of their tech-specs. Seems a bit of waste of resources though since they only used the crystal tools for a handful of games so far and like all engines CT has probably also been updated several times by now. Luminous is most likely just the 2.0 version of Crystal Tools anyway.

I know I'm not the greatest fan of XII's non-gameplay but one thing I'm absolutely sure of is that XIII is still the most Jaw droppingly gorgeous game when it comes to the technical side of the graphics.
