Why not release G1 in mainstream toy market?

[kup]

but kup, HasTak have reissued Bumblebee and Jazz in recent times and I don't think either Porsche or Volkswagen took legal action against them for it. There must be some legal clause that allows HasTak to reissue Transformers based on licensed vehicles where the mould was made a long time ago -- cos otherwise why hasn't HasTak been sued for their reissues of Jazz, Bumblebee, Sideswipe, Red Alert etc.? These reissues only came out fairly recently (especially Encores).

As I mentioned, that's because those molds are old. The mold itself is now owned by Hasbro not VW, Porche, etc. Legal ownership was taken by Hasbro way before the corporate world turned trademark infringement prosecution as a viable form of revenue. It would be too messy to sue someone who legally took ownership of something 25+ years ago.
