From the sounds of those with the box it will be maxed out once Alien is introduced. Since this KS has an estimated delivery of June 2017 and I assume another KS for the next One Night in Aug or Sep of the same year it will be obsolete soon. I'd hold off for the inevitable bigger box that is offered in next years KS campaign.
Of course, I have no inside information on any of this but that is where my head is at.
As a piece of art and pride and potential bragging rights... you can decide for yourself how much those are worth.
But for something to store and transport cards in I don't think it reflects good value. After seeing the addon price, I've opted to go for a non official solution, like a cut to size flight case or somesuch.
