Every time a new Trackmania has come out (TMO -> TMS -> TMN) the community generally went with it. There were exceptions, but the majority moved to the new game. However, when TMN came out, it was the first time there was a free TM and it was the first time the game had the chance to go to ESWC. Even when TMU was released, the majority of the people who purchased it were those who had owned previous TM's or had never played any form of it before.
Most of the TMN players remained in TMN, and even got angry when TMNF was announced. Also, a few players of TMO and TMS never moved to TMU because they considered it a waste of money when they weren't getting anything "new" but instead just old things redone.
TM2 should bring these players back, but the TMN players are likely going to stay in TMN.
