GSP hadn't fought for 4 years, and he left at a critical time in the UFC, when the promotion was transitioning into a new generation of fighters. The PPV still did pretty well. You have already said that most UFC fans are not that knowledgeable, if that is true, how does an interim belt further confuse them? All they know is there will be a fight. if they like the fighter, they will watch, if they don't, they won't. So, the projected negative impact of adding the 165 and 175 divisions is not based on anything real. The more belts there are the more chances for certain fighters to get a shine. I will stop there, because it is obvious that you have a personal negative attitude towards two more divisions, and so you are looking at it from a doomsday perspective. However, for every negative thing you say, there is an equally positive side. It all depends on personal outlook. The sport is based on celebrity. Naturally, the fans will remember celebrity champions whether there is 1000 divisions or 1. Those fighters who can fight and promote will be at the forefront, those who can't, will be ignored. This phenomenon is not "how many divisions there are" dependent.
