Every release has been a slightly different version of the original.  When comparing the original to the Silver and Gold, the only difference is that the materials Max used to craft the latter are significantly higher quality.  I believe that the original served as the catalyst that propelled and funded Max's true vision for what they wanted Kialara to become.  I don't think we will see the original design used again, just better varients of it, as we have been shown each and every time a new version is announced.  All that being said, I'm glad Max chose to destroy all the parts for the original design, because that act has given us all the different versions we have today.  And to quote MJ, that's just my "Two Satoshi" opinion on the matter.
