It's probably part of the deal to avoid competition against hasbro directly... so higher price point, no direct threat to Hasbro's market. This and the fact that they are not oring. It would have been great to see a collaboration super7/hasbro for mass market joes figures.
Anyway, regarding super7's stuff, I have only the alien figures (first movie, kenner retool of the prototype) and they are very nice.
Some super7 vehicle would be nice... A flagg to display all those sailors? lol
