i really hope they do with monk what they did with druid - basically take the class and turn it into a power source. Hence we have leader druids (shaman), controller druids (druid), and defender druids (warden).
If 'ki', as a power source, is treated as 'monk', then we can look forward to the joy of having potentially controller, striker, defender and leader monks. Name a fighting style for each role and BAM - all my Christmases will have come at once.
