Just went to one of the preview events at the Sony Centre at Funan. It was run by Esther, Sony Singapore's cybershot product manager who went through a brief marketing presentation. There were 4 or 5 units to play with.
Key points: the pre-order bonuses are a) the tan leather case (which Sony thinks is worth $139) and b) a Sony 16GB SD class 10 SD card. Esther said that this represented about $160 of value for pre-ordering.
Viewfinder: the VF is activated by pressing a small catch on the left side of the body. The VF then pops out vertically and you then need to pull the eyepiece out horizontally. There is no friction or other lock on the eyepiece, so you can't really brace the body against yourself for extra stability. Anything more than a light press against my glasses just pushed the eyepiece back in. Quality seemed quite good, reminded me of the EM5 I rented once.
Controls: I couldn't find a way to move the selected AF zone/point without diving into the menus. The Sony staff on hand didn't know how to do this either. The 4-way D-pad can't be used to do this as far as I can see.
Spot meter: there is a spot meter function but it only uses a spot in the centre. There is no way to move this spot. It wasn't clear to me if matrix metering is weighted towards the area that achieves AF.
Notes: it was interesting to see from the presentation what Sony thinks photographers want and who their target market is. Esther was keen to emphasise the built-in distortion correction functions (example given "if you have a group shot with a lot of people, the girls at the edge won't complain that they look fat!").
I will buy one but I won't be pre-ordering at this price. It's a pity Sony didn't see fit to throw in at least a spare battery and an external charger - I think that would be much more useful to your average serious photographer (and who else is going to be buying at $1200?!). At $1200 I'll be looking at HK or US sites.
