How much benefit on an FT sensor might be a bit questionable. The circuitry that takes up space from the photosite in a traditional sensor is more or less of a fixed size, irrespective of the pixel size. So for a compact camera with a tiny sensor, the circuitry is a large proportion of the total pixel size - putting this behind, as in a 'back lit' design makes sense. For larger pixel sizes, the benefit is smaller. They also, currently, have issues to do with cooling as they make the sensor thicker, which doesn't help noise.
