I too took notice of the attitude change in the image couplet. I hesitate to infer speed or rate of pitch decrease. However, to see a decrease in Pitch at this point in the landing is strange. I consider it possible that the crew are trying to 'plant' the a/c, dive at the TD point. That is a mistake, so would be doubtful. Wind shear was not reported and the bank is neutral.
What do you make of the velocity at the impact point? I tentatively put it at 100 knots, though that is a soft number. Possible they initiated a very late attempt to GA? Had they applied thrust at any time, and not met minimum energy to rotate, or rotated early, well, that would be the ball game. As with most accidents, there will be a chain that makes all clear, but only with time and analysis.
