Surprisingly, the Sony Rumor Mill has stated that Sony is planning to release a new APSC camera. Several sources indicate that this camera will have greater resolution and better autofocus than the present APSC format cameras.
The new camera is being touted as a "Baby A1" or a "Mini A9"... However. I remember before the A6600 was introduced, Sony Rumors touted that as a "Mini A9" I am quite satisfied with my present cameras but, the new camera might just be interesting, if it has the capabilities that the Rumor Mill indicates

It is APSC but, actually, for the majority of my uses, APSC format is just fine...
