There are many different type of collectors out there. Some collect for pure enjoyment, others collect for investment, and some collect for both. I should have clarified that Hot Toys is angering the type of collectors that collect for the 2 later examples.
I think it's great that they are re-releasing for the collectors who missed out on the first. It just sucks for the collectors who were their from the beginning who bought the first one only a few years back, only to have this same figure being re-released again. I also feel bad for the collectors who spent hundreds of dollars on ebay for the Ironman Mark I, only to find out that Hot Toys is re-releasing a 2.0 version of it. These are the collectors who are probably upset with hot toys-the ones that were with them since the beginning and got in early or the ones that missed out and paid the crazy aftermarket prices on ebay.
I have to admit, part of the cool factor was the fact that their prices went up in value because they use to be scarce. It was a nice extra bonus to collecting such detailed and awesome figures. I understand why some are angry that they are flooding the market with them now and re-releasing. There is no right or wrong way to collect. I just think that most people, whether they admit it or not, enjoyed the added bonus to see their figures go up in value because of their rarity.
