I know someone who works for Dodge engine testing, and he has not seen anything except for the hood that we have all seen already.

i think that a shaker will appear in the aftermarket, but its going to be difficult with the engine intake setup. keep in mind that the modern hemi doesnt get its air intake from the top/middle of the engine..it gets it from the very front of the intake, so for a shaker to work, there would be an intricate piping setup needed, that could be restrictive and costly on a factory vehicle, but ive seen them on rams, stratus rts, neons, vipers, lx cars...im certain that one will come from the aftermarket if these rumors fail to come true.
