If people wait on buying the first print in favor of a lower-printed reprint, then the first print never sells out, thus no reprint. The bottom line is that reprint become valuable when they become hard to find, because of the low print run. Now that lots of people are going to be looking for the reprints, the numbers aren't going to be particularly low. The key is that books tend to become valuable when they have some feature that people weren't previously looking for when they were released, but now are. That's what happened with Newsstand editions, previews/news magazines, reprints, etc.
