It will go FF in a hurry if Sony release a NEX FF, prices are dropping fast, and now there are small ones for cheaper than ever before. Sony might use this as a wedge against DSLRs which cannot be reduced much more. All the new FF lenses are designed for beautiful bokeh on FF, a huge difference. Very few prime lenses are made for APS-C, it is seen by makers as a transition/entry format. You learn to see the differences over time, just as with MF after FF - an easy drawing style with better tonality and (generally) DR. It is very nice to use lenses just as the designer intended, like a full anything, not 2/3 of anything.
