I frequently encounter a lot of confusion regarding the "wave" system used by Hasbro and other toy companies, so I thought I might try and explain it so people actually kow what they're talking about. Please note that this is not intended as a slight against people who just don't know any better. What I see is that different people have different ideas of what a "wave" actually is, which then leads to confusion when those people try to discuss with each other. So I thought I'd explain it in a way that people can (hopefully) understand. If I come across as too condescending or didactic, please let me know. Before I start, some notes on the terminology used here: I use the terms "assortment", "size class" and "price point" interchangeably. Likewise, the terms "wave", "case" and "case assortment" technically all mean the same thing, but since the general conception of a "wave" is not exactly identical to what a "case" or a "case assortment" is, I will try not to mix those up for the sake of clarity. Each of these will be in separate posts so this first post doesn't get too convoluted. Misconception #1: A "wave" is a giant bulk of numerous toys of all sorts of price points/size classes that are all released at the same time. Misconception #2: A wave always only contains new figures. Misconception #3: There is such as a thing as "one true way" of counting/numbering waves.
