The biggest areas for me where Iminime and Rainman aren't on the same level is still tailoring and accessories, though that could well change. Iminime has drastically improved. But the motivation for Iminime producing X or Y isn't just that it is a character that could use an update. It's mostly whether or not demand exists. Take the Dude or Butcher. I think Rainman's figures are damn near perfect, and have a very hard time imagining any major improvements. But how many people would jump at paying $500 for something close to what Rainman gave us? All it needs is a certain number to express interest, and Denny will apparently go after it. So, I can see something like Alex from Clockwork (though that sculpt really could use an update IMO), the Dude, or Bill being done by Iminime at some point.
