I'm definitely in for a locomotive and caboose. But I'll echo Dave's comments above, in that I think the artwork ventures a bit too much into the realm of a comic-book appearance for my liking. So I'll wait to see what's actually delivered. I'd prefer something closer to the WWII-style artwork -- i.e., closer to what Menards has done with their WWII nose-art boxcars and Lionel has done with their Coca-Cola boxcars. The MTH images are OK -- I just think if they'd pull back on the comic-book effect and stay in the realm of subtle HDR filtering of a real-world image, they'd really hit the mark for a winning set.
Having said that though, I give MTH lots of credit for offering something unique like this. No company is ever gonna offer something that EVERYBODY likes. But it's good to see them out there offering SOMETHING different and eye-catching. Personally, I'm not into buying stuff anymore just to own an entire set of something. That's not important to me. However, I can easily see where this locomotive and caboose could work well with my existing military consist, so the freight cars just recently announced aren't a "must have" for me.
