The hybrid AF certainly is the interesting part for me. Nikon did hybrid on the small sensor, Canon tried on the APS-C and we will see what Sony can do on the APS-C. A NEX-6 is supposed to be coming soon; also with hybrid AF.

I could care not care less about the phone connection, but the Wi-Fi is important in that Sony does not have a wired tether on any model since the A900 (no Live View body has tethering). Wi-Fi could offer an elegant tethering solution if it's fast enough.

Rumor says that the new FF DSLT to be announced next month will have both main sensor/hybrid PDAF and SLT PDAF.

I am watching the main sensor PDAF closely. To me, the complete removal of the mirror and then the electronic shutter will be the most important developments of this decade. Now, about that mechanical aperture...
