Can and will are two different things. There are a lot of corners cut in phone cameras to bring them down to a mass market price. "Progress" in these materials and processes is in reducing costs. For example, antireflection coatings that can withstand the high temperatures used to bond the multiple layers of lens wafers onto the sensor, thus reducing the complexity of the assembly process. If, as a side effect, it makes the optics slightly better, that's just a happy coincidence.

So to think that the latest technology in quality optics and sensors will go into a phone camera is silly. It's possible to create really excellent cameras that size... but not in a $600 pocket computer.

If you like an analogy, look at automobiles. There's been a steady increase of about 3% (IIRC) efficiency every year for decades. Does that translate into better mileage? No, generally not...the market has been driven by talk of HP, 0-to-60, hauling a ton of stuff up a hill, and other such testosterone-induced nonsense. So, the improvements in technology don't go into improved fuel economy--they go into more powerful engines, "more headroom" and more gadgets.
