If you're meaning me, by chance, no. I think what a lot of people are getting at, is that a boxy car is a hot item right now, and that's why so many other companies are now getting publicity from theirs.
All it takes is one company to do it right, and then all the others follow.
Like I said, I'm more than certain that most of these box-cars have been around for ages, heck, the bB debuted in 97'
