I imagine monks, and samurai, ninja and sohei, as class with ki as power source. A psionic monk is possible, but as subclass. Psionic and ki may be linked, but they aren't the same (and incarnum and ki also are different things, aren't they?). And the most of martial maneuvers by warblade, swordsage or crusader, the martial adept classes, should be ki, but spell-like effects, then theses should be arcane or divine magic.
The psionic mystic has got a different point of view. The wizard studies, learns and investigate, the sorcerer trains to improve her techniques, like artist with her tools, but the psionic is training with herself, as an martial artist champion whose body is the own tool. If a wizard or sorcerer wants better tools to work, the psionic wants to improve himself to get the personal perfection.
* How would be the mythic psionics in Kara-Tur or Zakhara? And how to be adapted to a videogame?
* Wouldn't you a psionic class about astral constructs being used as exo-suit, powered-armor or monster pet?
* Other matter is about creatures with telepathic powers being used as demi-PCs, sidekicks or monster pets. A player could ask to can use two PCs if both share a telepathic link.
* Psionic subclasses aren't a bad idea, but we also need a psionic base class, at least because some psionic prestige classes have to be recycled as subclasses.
* I have suggested in the past some partnership between WotC and Dreamscarred to publish some things about psionics power, martial adepts and incarnum/akasha.
* I have said some times Ravenloft will come back, but not only as TTRPG but also with projects for the mass media. (Now my crazy idea is a dark domain in the shadowfell set in the pulp age, where the decepticons, the evil transformers from planet cybertron, are dystopian tyrants. You are talking within your car, or near it but this may be a spy. How would be the masque of the red earth in XX century, with a panzer-punk look like the games Wolfenstein, Tannhauser or Reich Busters?).
