Unreleased Robot Heroes on ebay.

[griffin]

The 2 sets that were cancelled (RiD Optimus Vs Megatron, JP G1 Star Saber Vs Dezarus), were on ebay (out of packaging) from a HK seller, suggesting that someone got their hands on pre-production samples.

Maybe this means the moulds were actually produced, which would mean we should see these four eventually somewhere, for Hasbro to make back their investment into producing (expensive) moulds.
