It is simply marketing, isn't it?I honestly cannot think of any possible reason they would want to do something like this.
Even as a consumer I can't think of any possible benefit something like this would bring.
I could understand it being done if LightWave was in the same position as Commodore and therefore something like this being done by the fans to cater to the retro market, but since LW is still a going concern, your proposal makes little sense to me.
And there will always be collectors.
I love the way it sounds having a BSG Lightwave3D edition including some scenes form the actual series...
Or a blood and chrome one!
Can you not magine how much people or potential users could learn from those scenes used for the series?
On the other hand, there are plugins that only work with older versions or only even on 32bit versions, or different versions of the render engine some people may prefer using.
I deff see a huge potential on that, sorry.
