I've said this before, and I will say it again: At the 1999 RCHTA show at the Rosemont IL Convention Center, AMT/Ertl showed box art for these same two subjects. Those were, according to Tom Walsh--then head of product development for AMT/Ertl, last minute proposals to the hobby industry. Walsh told me straight up at that show that it did not look promising for either subject, as Walmart and the other "big box" retailers (who pretty much controlled what new model car kit subjects would see the light of day back then) had rejected them for their 2000 store "resets", and it was hoped that local hobby shop owners and hobby wholesalers would bite on them. They did not, at least not in numbers sufficient to warrant their development into plastic kits, so the idea died on the vine so-to-speak, at that time.
That's the delay I was referring to. I knew I remembered this being announced once before, but not 12 years ago!
