As a new to the minimate scene father of two boys, I would like to see more standard issue versions of characters. For example, I want Power Man and Iron Fist, but I don't want to buy the original set through EBAY, I don't want to pay over $8, and I don't want a version of their costumes that were only worn once, like "Time Traveler, Full Armor" Iron Fist or whatever. I just want an Iron Fist figure where he has the green suit, the yellow mask, the yellow slippers and a fist of iron.
Also, accessory packs.
Additional thoughts, when I was a kid, there were action figures (I forget what they were called) where they were about the same size as Star Wars figures, but they were regular people. There was the tv news crew with a van. There was the guy on a motorcycle. There was the camper with a roll-up sleeping bag. Something along those lines would be cool for minimates, especially if we could put Captain America on a motorcycle.
Also, micronaughts. Those toys came out when I was a kid and they weren't based on anything else. They were kind of space warriors that you could play with and invent your own stories and adventures. I wouldn't mind seeing something similar in Minimates.
Also, I would love to see the original micronaughts in minimate form, especially if they could do it to coincide with a re-release of those old comic books (which are hung up in limbo because they were originally published by Marvel but Marvel doesn't own the rights to those characters).
