I don't think Tron VE is going to work out for Stern. The numbers are not that big in resale that a new machine, which will costs around 5500 euro in europe, is going to justify a new pinball. Even a Spiderman VE will be hard to sell, the only way they could stir things up is as a comic art edition. Then you could get some of the owners to sell theirs and try to get 1000 machines out. As the VE edition is about the numbers they need to get that kind of sales. There needs to be real added value. There are some nice machines on the market for that same price.
But hey it's Stern, they know what to do....
