You all forgot(or did i miss one?) that competition between so many manufacturers, and tamiya's abdictating the throne leads the model production world into a maelstrom(lol) of whirling death. If one of them screws up, they could destroy their entire outlook on the future. Tamiya, i think has gone a little crazy, but it is nice to know, that you can make a dio of a tank destroying a plane in scale withought trying to find one or the other in scale...
But, a great benefit for us is, more extras, better molds, detail, accuracy or price!
take your pick, they are all out there now!
