Thanks for the explanation.
So, basically, they took the route that almost no one wanted (lumping everything "asian" into the ki power source), it didn't work out for obvious reasons (I've argued countless times that lumping Wu Jen, Shugenja, or even the Ninja into Ki is pointless), and thus they chose to scrap it entirely rather than come up with a set of new ideas to actually make it work and create something that adds to the game. Somewhere in there they arbitrarily decided to fuse a mechanic into an entire power source for no good reason. And now we have the Monk as part of the Psionic power source, diluting and confusing both the classic idea of the Monk/Ki-user/barehand-fighter class and the entire idea of what Psionics means.
I still remain entirely unimpressed by all of this. I guess I may as well hold final judgement until the class is actually released in the PHB 3, though. I will continue to mourn the loss of all the great potential the Ki power source had, though.
