Seems that Samsung closed most of "my missing feature list" items

let me see what I complaint about when I first used the NX20

1. consumer only WiFi implementation: the New V3 APP and the dropbox integration seems to address most of that, still haven't seen any indication that NX30 supports transfer of RAW

2. lacking customization on iFN and buttons: seems that the new i_Functionplus feature will address that. I am eager to see how far that goes. I would like to be able to re-assign a frequently used function onto the WiFi button.

3. Flash Sync speed to low: seesm with the new SEF58 they addressed that

4. Wireless flash options: comes with the SEF58, whereas I have not seen any pricing for the new flash gun.

5. The EVF diopter changes its setting to easy: they now placed it inside so thatit can only be modified when you pull the EVF out. Smart solution for a real issue

6. A lack of a serious Zoom lens: expensive but very promissing

7. lack of a very small Zoom: the new pancake zooms seems to be a good lightweight travel option (but it has to prove that the optical quality is on par with the 2050)

8. AF-C/Tracking AF: the Hybrid AF with the NX300 was already a step up for me. What I believe will be an improvement is the new lens motor drive as the NX300 only benefits from newer lenses designs while some of the older lenses showed no real speed improvements.

9. Design.... well, they kept the NX20 design  and did not try to place the EVF at the side (being a left eye shooter)

and they kept the price in a reasonable range (especially when you include the LR5 SW bundled)
