Looks like it's available for ~$200 as well. That's still pretty pricey, but I bet the $2,500 is due to some weird pricing arbitrage or something, you see that with used books fairly regularly on Amazon.
The $2500 one is, if I'm not mistaken, a limited signed special edition (they only printed a couple of hundred copies). The $200 one is the regular edition.
(Disclaimer: I own one of the regular ones, and didn't pay $200 for it. But it's a large form factor hardback printed on high quality glossy paper -- full of breathtaking colour images -- so even if they reprint it, don't expect to see copies on sale for less than $50.)
That sounds a little more reasonable. Hopefully they do a reprint, I am a big fan of those large format coffee table style book, presuming it's about something interesting.
