amblepath: I think that picture of the whole stable of 4/3 lenses with the Om-D made the nex system seem pretty sparce. This announcement is I think a 'don't jump ship they are coming' type of announcement.
the m43 lens look comprehensive but alot of them are just updates to previous. And duplicates across brands. how many 14-42 lens does anyone need?. There are really only 3 gaps with NEX compared with m43 - a super wide zoom eg 12-24, a long tele zoom eg 100-300 and a G lens to compare against the new oly 12-50. All of these seem to be on the new roadmap.
the button with 2 dials that change function on button press harks back to the Dynax 7xi film camera from Minolta from the early 90's which used this approach. worked well then - promises to work well now. Cant wait to see a Nex 7 in store.
