I did this last March, and I did get the 25,000 mile bonus a few weeks later (not sure why it's only 20,000 now). I just checked my statement from March and it took exactly three weeks. Not sure if it will happen this time but that's a pretty quick turnaround for that many bonus miles. An awesome conversion to get 152,000 miles and a 7 night stay. I'll do this every time if it keeps occurring.
