It seems to me that given 4e-style niche protection, the energy power blasting ought to go, at least as a major schtick (this is clearly the domain of 4e arcanists in general, and wizards in particular). And that probably goes for astral constructs as well (summoning really belongs to a dedicated Summoner). Mind-altering powers definitely should be one of the better psionic options (and probably the one thing the psion [or possibly telepath] best at).
As for ectoplasm... never really bothered me much.
