Tom,
You didn't make us mad.
As for future expansions, it's really your choice! Really, it'll depend on how well the first set is received. If people hold a grudge and shun the UP, then we won't continue -- I try to put out what people like, simple as that. On the other hand, if users like the set, as I think in many ways it's an improvement of our earlier work, and one of the best we've done so far -- then we'll further develop; we have some ideas floating for bonus models. I confess that I myself was ambivalent at first but have come to appreciate the finer things the company represents -- after all, the UP is the largest US railroad and has a wealth of history and astute management behind it. From a modeling standpoint, I see how many interesting locomotive types they've owned -- it's a bountiful road. And finally, in the near term, we're looking at creating new sets based on the heritage UP properties, so you can rest assured they won't be forgotten, either.
cheers
