Hot Toys has raised the bar and Sideshow has seen that. Personally I want the very best expression of the character possible - the price is a distant second to that.
Now some may argue that they don't need to price it at $90 even though it's extremely detailed, required 3 times the R&D of a Star Wars figure and has elven runes on his culottes.
But Sideshow doesn't need to gouge - they want to sell figures too. So I'm sure the pricing for Gandalf is based on a formula, the same formula that gave us a $50 The Dead figure. You add up the development expenses, license expenses and production expenses and you come up with a price that will allow for the standard percentage of profit the you earn for all the other figures.
Well said. I completely agree.
