Yeah now that you mention it, I do remember seeing a few new pieces in my friend's copy.
Either way, now adays when I pickup TROs I find I just look at the stats and the artwork as a lot of the fluff seems redundant (how can you write development background for 500+ units or whatever and keep it fresh??).
So if a book doesn't have a lot of new artwork, like 3058U I just don't pick it up. But if it does, like 3055U I do.
