My experience as well as anecdotal evidence would say that if you go over the 50K threshold this year the MQMs will post this for this year. This is true even if you wait until 12/31. The unfortunate thing is you lose 10K MQM/Miles if you don't, but you lose 15K of rollover if you do. You can try it and see if you luck into an early 2010 posting date. Worst case scenario you become PM.
