Quoted from evh347:
I’m hoping the next run of these is on the line soon.
At the Rocky Mountain Pinball Showdown I talked with a couple of guys from Chicago Gaming Company and they said right now they are on a batch of Monster Bash that should be finished by July 4 at the latest. Once MB is done, they will start the run of MMR. They did also say that most of the machines are already spoken for, so get in a preorder quickly if you have not done so already. They said I can expect to receive mine at my house late July or early August.
