If sales indicate your product is a hit, it's sold out everywhere and despite QC claims is fetching ridiculously absurd prices on ebaY, why would you change a thing?
Again, the company didn't even deal with the issue until embarrassing pics were being spammed on their FB page. And then, they switched their page to company updates only and handled everything "hush hush," made customers jump through hoops, refused customers who bought from ebay (which excluded every US customer who didn't purchase it through DCD) and only allowed a single replacement regardless of whether or not you provided them with a receipt showing multiple purchases, and even those replacements leaked. HT was able to sweep it nicely under the carpet because overall, in the end, the figure was still a financial success.
It's believed that the only reason changes were even made to the DX02 is because the issues were leaked to DCD and they didn't want to lose the license. While admittedly that's speculation, it's highly probable.
If true, what a f-in disgusting company. HT doesn't deliver what people paid for and instead of fixing the problem with the product for everyone, they screw their customers over.
Edit: In short, the problem with the suit was probably caused by greed and the "solution" was handled in the same way.
