I think we need to see the Nex as what it really is. A PNS with interchangeable lens.
Perhaps we have seen the PEN and GF1 and hence we keep thinking the EVIL sys will be rivals to M4/3 , but from the design and layout of the next + the pricing , its very clear that Sony is targeting the masses , people who doesnt know much abt exposures , apertures and ISO.
An average consumer is mainly concern about size , quality , megapixels and zoom. Some of them never shoot in any other mode other than auto + other presets ( night mode, potrait, etc)
While for the most of here, who demands more than shooting in auto, the interface becomes challenging.
I am skeptical if SONY can come up with an advance manual controls enabled NEX, at the same size. The only thing I can think of is to incorporate their PS3 motion sensor technology lol , move the camera up down to change shutter speed /aperture . That would be COOL
