It's so funny how people get upset when a company tries to make money. As someone who has always been an early adopter (technology, toys etc.) I accept the fact that bigger and possibly better will always follow my initial purchase. It happened with the iPhone. Was I upset when the new cheaper one came out? NO! ABSOLUTELY NOT! I paid a premium for owning the iPhone earlier and never regretted it. When the new one came out, I gave my old one to my dad and bought the upgrade.
Hot Toys isn't a charitable organization trying to help those in need. They are a company that wants to get the most out of a license that they've spent a lot of money on.
I honestly think the DX line is a direct result of the quality of figures being released by Enterbay. Hot Toys is trying to add some features and expand into an even more niche market. I personally think it's great.
If you don't want to buy the figure, don't. I remember when Lucas released Star Wars for the umpteenth time to dvd. He finally relented to fans and added the original, pre-special edition versions as a bonus. In this case they were 4:3 and pretty crappy quality. Now I know for a fact that HD prints of the original trilogy have been cut and broadcast in Europe. Lucas decided not to give us those versions, so I boycotted the release. No problem.
At least HT is upgrading the release.
