HT pretty much killed its own iron man and predator franchise with a combination of price increases, rapid repetition (how many f versions can you make of the same red suit and predator), and unlimited runs(ES for the later versions must be in the 5000+).
If you look at ebay and for sale threads the prices have been dropping every month. The $500 iron monger is the final straw. There is a threshold for those plastic toys, after which people just give up. Ask yourself are you still as excited about a new HT iron man and predator as a year or two back?
Greed is good, nothing wrong with milking the customer base for max profit $$. But those guys are throwing bombs in the pond trying to catch fish, instead of leaving some to repopulate for next year. Eventually the pond will be empty. They are going after batman now...
I used to buy every HT iron man and predator, but have stopped cold turkey and cancelled a bunch predators including the shadow version.
