For items that already exist (such as most of the force box sets, Judge Dredd, Brit-Cit Judges, etc) we are already manufacturing to cover pledges. These we will dispatch as quickly as possible after the Kickstarter ends - while we do not know how many pledges there will be at the end of the Kickstarter, we will be working to get these items out to everyone within two weeks of the Kickstarter ending.
Other items are currently being designed or are in the queue to be designed; manufacturing naturally follows this, so there will be a time lag. For some items, like the Lawmaster and Manta Prowl Tank, we are already prepping manufacture, and so they should follow quickly. Others will take a little longer - however, if you have pledged for some items that are already being manufactured and others that need to go through the design process, we will not hold your miniatures up until everything is finish. We will send items out as they are ready, so you will not have to wait long to start seeing some Judge Dredd goodness!
