TTown - when you decided to join your brokerage, did your broker give you any sort of a commission scale or did he/she tell you only verbally about the raise in your commission split after you sell $1.5 mil? Did he/she tell you how much higher it would go and if your commission would then roll back to the 50/50 after the beginning of the year or your start date anniversary? It just seems like they were being very vague with you when everything regarding what you can expect should be presented to you up front, in writing. If I were you I would go in there and get something in writing up right away. You might want to check your Independent Contractors Agreement first to see if it mentions anything in there.
