Despite the fact that I really like psionics, I voted "no".
The fact is, neither the PHB nor the DMG are getting enough new pages to justify the inclusion of psionics. Psionics rules would thusly have to be cut down and trimmed to a horrid degree just to make them fit the page count. It would also invalidate the previous PsiHB, and I've had enough with having just three books I spent money on be declared worthless, thank you very much.
I'd go on about how bad an idea I think putting psionics in the revised core rules is, but for the fact that I feel totally confident that they won't do it. WotC knows they can't squeeze it in, and they still want people to buy the PsiHB, so I'm not worried.
