Logic dictates that they hold off the reveal until the PPV, or the first show after it.
Having Joe/Daniels/Tomko/Moore/Raven/Don West uncovered now would simply confuse the booking going into the PPV.
My pick for tonight's interesting development in 3D. Last week's finish makes me pretty confident that they're turning heel with Rhino, and since they don't have a match for Turning Point (Turning Point is next right?) it's possible that they might make the change tonight so that they can fight Morgan and Supermex (an interesting team, but something of a step back for both guys).
I am of course also looking forward to seeing the fallout to Desmond trying to separate Kurt Angle's head from Kurt Angle's body. Fantastic stuff going down there.
Tera is apparently fighting Daffney, who should still have a broken arm, so I'm not sure what's happening there, possible another angle with that MMA woman. I'm fast coming to the conclusion that Tera is a waste of space who only got over because of the shit she was surrounded with anyway, so I'm not bothered too about that.

Oh, and somebody might mention Hogan at some point, although the absence of massive front page headlines reading "HULK HOGAN DÉBUTS AT IMPACT TONIGHT" more or less confirms that we're not getting anything major.
