I'm just going to assume that what I have to say has already been said, purely based on the size of this thread. Reading through a bit of what has already been posted there are a lot of ideas I really like. The main thought of, "Psionics shouldn't be another mage with different flavour text.", is something I really agree with. So while it may be a lot of working completely reworking psionics from the 3.5e material already available it could be in Pathfinder's best interest to introduce Psionics as a form of, but complete seperate from, monk. Where monks are the physical perfection of form, psions could be the metal perfection of form. Less focus on an oriental perspective, but with the same feel and mythos to the class.
