Supposedly the fingerprint reader anywhere than the normal place has been ruled out, so the only question is whether there will be one at all. If they believe the 3D facial recognition is significantly better I suppose they could drop the fingerprint reader. Personally I'd rather have both options since each would have their disadvantages (i.e. gloves, sunglasses) but we'll see. My money is on it under the glass, though maybe it doesn't work quite as well as it did previously as a result.
