I could give you quite a few examples from TF and Joe (canned or just damned impossible to find).

In fairness, they did release on 30th Anniversary cards most of the army builders from the end of the Pursuit of Cobra line that were absolutely un-findable in the US, but not all (cough, Rock Viper), and none of the individual characters.

On a related note, could the more high-demand figures from the last Vintage wave be re-released on whatever card they're doing next? I'm thinking that Emperor's Guard figure is going to be a pain to get, being an army builder and all.
