the demand on them is pretty high.
Who got the rights to it? spielbox? or HiG?
Not sure. Some are from the magazine(s) etc. But it would stand to reason if they all came together for the release they would all profit.
3 partners claiming 3 USD each net profit for 100.000 copies is 300.000 USD profit for them (rough figures). Even if the sale for an expansion pack as this ends up at 30 USD it beats any alternative fans has atm.
It has been mentioned before, alternative is to get the graphics and print them out yourself. There's nothing wrong with this. Sure it may sting as it's not original, but you do get to play with the expansions!
I am myself quite the original only parts, but I can see myself printing out those caverns for a fan-making expansion I'm working on.
