Not that I know of but theres sure to be at least one more set in 2002, I'm assuming your talking about the die cast figures made by Rocket USA?
Anyway I think that the next set will probably include Zapp, Kif, Mom & Url, i'm only guessing. I hope that one day they make Beelzebot and Roberto too.

edit-I see that your not talking about the Rocket USA figures, I just went straight into the thread without looking at the title thinking it was the general merchandise thread, which it's not. I can't be arsed to delete what I said, take it or leave it
