@Matt - while I'm a big fan of the brown/duck color, I too would not pay $400 for those. NBs do seem to be fairly well made, but you'll never get a solid price per wear out of those at that price.
My sense is that pair will come down in price as soon as primary stock is limited.
The sneaker market as a whole has come down significantly in recent months. Maybe not for all pairs, as it is a hype market, but as an example - my purple/black Dunks that I paid close to $300 some 12-18 mos ago, are now going for under retail (sub $100). That said, if the hype isn't serious, you should be able to get into a pair of those $400 NBs at half that. Of course that is assuming you can fight the internal FOMO while you wait for the hype to subside...it's all a head game after all.
