I don't think this is portentous news of any grim degree. They know what they're doing and I highly doubt they would pay for the use of an engine if they didn't have plans for it. It's no reflection of where they may be taking the game, I think, merely a reflection of, as Sy said, the fact that development time/cost are getting out of hand for just about everyone. If they're going to be building on the concepts they set up with FFXII, I can't imagine XIII being lousy. A really good next-gen engine should give us some pretty amazing results in the end, I'd say!
