I think Hasbruh™ has taught us that $99 is a magical price point. People instinctively think toys over $100 are "expensive". I would not be surprised if Dart Zone keeps the MSRP down to $80.
It shouldn't go over $150 in my opinion unless they start selling it with the max Stryker and mk ll all together. The Mk l.I was 150 as well but it was just a nexus pro with 240 darts so...this should in my opinion be around the same price.
