Ha, I knew it was odd they never called it "limited" or gave a number for this overpriced guide (if you didn't catch it from amazon at 40% off). Piggyback was being typically opportunistic after already releasing a "collector's edition", put out a small number of preorders to create hype, and jumped at the chance to put more out there. Three versions of the guide is really pushing it though, especially knowing zelda fans are the type who will want each one for their collection.
At least they give people a chance to cancel before announcing this 2nd print and not waiting until it releases. I bet most orders were just because of the perception it would be rare.
As for art and artifacts LE, as the zelda hype is slowly fading, aftermarket price is probably settling around msrp. I still wonder if the total number of 10K for it is comparable to the 4K mentioned for hyrule historia, or if separate regions are involved. Price will probably go back up a little at the next zelda release when resale stock is lower.
