Make them fit the world, not be a strange piece of sci-fi. This includes ignoring names like psion or psionicist.
4e had some nice ideas about incorporating psionics into their game, linking it to ki and monk powers wasn't a bad step. Or the Pathfinder Occult Adventures classes that are being currently playtested and can be seen as Paizo's version of psionics. The psychic magic those classes use is described as being drawn from concious mind, life force and cosmic sprit.
Im not saying that the old sci-fi advanced mind idea should be thrown aside, no, i think both should exist in the psionics chapter, but the "sci-fi part" should be set as an option to those who want it that way. Have classes and powers named more "fantasy-like," but leave the sci-fi/pseudoscience ones as options in a chart or their descriptions.
About classes... well i don't think we need more than two classes: Psychic Warrior and the "Psion-class." I think others might fit right under them two.
