The biggest change is also the reason the numbers got dropped from the names.
Which reminds me how I prefer the way they used to do it, with actual names for their bindings. The whole numbers/letters things started with Japanese luxury auto manufacturers like Lexus/Infiniti/Acura copying the Euro formula (think BMW/MB/Porsche/Ferrari) and trickled all the way down to snowboard bindings lol.
