Keep your eye on the new sensor-shift technology appearing in some Micro Four Thirds (MFT) format cameras. Some new cameras allow you to take a 40 megapixel image using a very small sensor. Currently this technology only works when the camera is used with a tripod. But perhaps Apple's new photography "breakthrough" is related to this.
How does that help when the problem is with the lense and distance to the sensor? 4 third third cameras tend to let in less light (but allow for more compact long zooms). This just compensates for this weakness by enabling a lower ISO. All that is great for cameras with a bit of space and better optics (which is what Olympus is doing), but not incredibly fantastic for smart phones.
