I agree with you on the numbers of LE's.
If the demand is high then make more, however it is supposed to be a limited edition so you have to have a limit. 500 is good I reckon.
The LE's, Premium's and Pro production is a great business model as it caters to everyone but I would think since the Hulk LE's sold out in minutes that Stern would rethink the amounts produced.
Just doing themselves out of the coin I think?!
