What I have noticed was that some companies like Round Two were reissuing interesting kits at a rapid pace every quarter. But recently they have basically stopped reissuing all kits, now I rarely look to see if any interesting kits are coming. If I ran a model company I would get the customers' opinions', I would come onto sites like model car magazine, scale auto, or coffin corner and get their views on what should be reissued. Than I would make a decision based on feedback, or I would come on the model forums with a list of cars that are up for reissue and ask their opinions. I have found that in the past companies like Rc2 started to become unpopular after they kept reissuing kits that people weren't happy with.
