They probably will, but i don't think their going to put much effort in it.
If they are going to do it they are going to do it right. If it is half--Yoinked!- then it wont make the cut. Imagine of the Kinect features for CEA were just thrown in on a whim? Sure what they have for it isn't anything ground-breaking, but that's the point; it doesn't affect the system in a negative way. The 3D, if there is any, will be of the caliber the rest of the game is.
This all said it really depends on how substantial the engine is. If they are pushing the 360 to near 100%, it may have to sit out until Halo 5 and the next system, or else risk quality reduction.
