Keep in mind that "seen before" is a consideration that generally only matters to people who have already been collecting a while. After all, LEGO City puts out a new police station or prison every year and it still tends to be a top seller, just because there's a new generation of kids lining up to buy it each time. Also, chances are these two locations will both appear prominently in the movie, so if they didn't release sets of the movie versions of them, a lot of kids and adults alike might be disappointed at having to pay inflated prices for the old ones online. I think the designers did a very good job making sure the new Batcave and Arkham Asylum don't just feel like rehashes of the versions we've seen before.I'm glad I'm not the only one excited about those new hand pieces! I've tried using the Chima gorilla fist pieces on articulated mechs but it's difficult. These should be much simpler to utilize. I hope they end up coming in more colors, particularly at least one neutral color.I totally get what you're saying, I was just offering my opinion. I'll admit the new Asylum set does look a lot better than what I remember of the old one though. I'm just not a big fan of the villain minifigures in it because they all look a little plain aside from their heads and hats/hairs. I'd most definitely like to see those hands in more colors too. Even with the color those hands are in right now, I could see them being used in something like Jayko or Nexo Knights MOCs.
