Would be great to see a massive art book beginning from XI to XIV. I guess there's still time as FFXIII-2 approaches and an art book can once again be compiled...perhaps even wait for Type-0 and Versus?? Doesn't that just make you squeeze juice?
I guess if The Sky art book includes the 'artist' involved with the game, it just makes it even more valuable as an artbook and a collector's possession. I'm sure once these get low in quantity, you'd be paying up to the sky for a brand new copy
[I'm waiting on the US amazon to open up their pre-order as they'll probably cheaper than UK or Canada]
