I find this a very interesting subject. But after reading through the thread I can't find a clear answer. A quick Google search turned up this text:
An airplane will stall during a coordinated steep turn
exactly as it does from straight flight, except that the
pitching and rolling actions tend to be more sudden. If
the airplane is slipping toward the inside of the turn at
the time the stall occurs, it tends to roll rapidly toward
the outside of the turn as the nose pitches down
because the outside wing stalls before the inside wing.
If the airplane is skidding toward the outside of the
turn, it will have a tendency to roll to the inside of the
turn because the inside wing stalls first.
If the coordination of the turn at the time of the stall is
accurate, the airplane's nose will pitch away from the
pilot just as it does in a straight flight stall, since both
wings stall simultaneously.
So according to this text it seems that Jeremy Pratt is incorrect? In a perfectly balanced turn the nose will drop (with the wings at an angle to the horizon) but neither wing will fall away.
I think in essence this is what SNS3Guppy is saying. Has someone actually tried this? Anyone who has tried all three variants should be able to give a us clear answer.
