Nice analysis, Dan!
The Apple guys certainly looked both happy and excited at making the announcement and expounding the benefits.
Makes Android look like a tech dead-end. The Flash of twenty-teens mobile.
"6 inch" tablet-phone seems more likely than a betwixt-and-betweener: As I've noted on this forum before, Apple is a metric company: a 10cm iPhone (one-hander phone), a 20cm iPad mini, a 25cm iPad, and now (it seems) a 15cm iPhone (a proper two-hander). And if there's another iPad, it'll be a 30cm model. 15cm would have enough real estate to do stuff (two-handed) that fiddly on a normal 10cm iPhone. And it would be a terrific size for games.
Had a Sony (Minolta lens) alpha DSLR a few years back and I liked it a lot (lighter and easier to use than my current Nikon D5000 while similar in picture quality).
It's a lot of money for essentially a compact camera replacement, but Exmor-R and the Zeiss f-1.8 sounds like a killer combo. Nearly 3 stops better than usual compact light gathering. Let's hope it runs on iOS-'simplicity quality' software.
An f-2.0 lens would be a significant improvement. Tiny cameras suffer not from a lack of megapixels but from low signal/noise, and f-2.0 would shine twice the light on the sensor as f-2.8 (though the current one is f-2.4, I believe).
Megapixels above about 3 MP are pretty much irrelevant in a phone camera format. The crop factor of this unit's camera (4) is half that of the iP5 (8) which should lead to a 2-fold better signal to noise ratio. The drawback is shallower depth of field. Hardly likely to attract buyers in droves from the iPhone (a iP5 and DSLR combo is what I use if the trusty Nikon happens to be with me).

So why so opinionated on what others should do? (I once did make good money selling nature photographs for post-cards, etc.).
The iPhone is the first, second and third most popular 'camera' on Flickr for a reason (apart from being the camera you have in your pocket). Take a look in Flickr: the iPhone takes really good images. Photography is about getting the image, not a camera-tech...
