It appears the camera is real and will be announced soon. Samsung is going to be the first MicroFourThirds competitor. I found some rumors here: k-rumors.com
And here the text of the rumor:
I heard this from a attender of the trade show in Korea.
He said NX10 was displayed with Canon 500D and Panasonic G1 (GH1??) side by side.
There was a comparison chart, but most part of the chart is hidden under papers.
He got impressed NX10 becomes fatter than the mock-up shown in PMA 09, but it is still very small – actually he felt it is the smallest one among 3 bodies.
It has best rear-display and shortest response time for user actions.
He mentioned NX10 seems to have almost equivalent AF speed to what dSLR has.
He saw 3 lenses for NX10 include a prime lens. The prime lens is very thin, and it will have faster speed than Olympus 17mm pancake lens.
Also he mentioned about the price, he understands that Samsung will set aggressively NX10 price. Since Samsung designed/developed most parts of NX10 by alone, Samsung has more room to control the price. It will be definitely less than its competitors. Even it could be unexpected price.
Samsung is very serious about new NX series now.
Rumors are becoming more frequent and more specific and may this is a proofe that soon (July 17th?) the camera will be released!
I got some information, no official, but I hope somebody confirm it.
-The prime lens is a (large aperture wide angle fixed) 35mm (35mm equivalent), maybe a 24mm APS
-The big zoom is not a telezoom (no confirm yet) this is a zoom like 18-200 or 18-250mm
-Nothing about the standard zoom
-These lenses has double focus system: contrast AF motor-assisted and manual focus limited. The second switch (the first one is for IS) allow to use the manual focus like SLR lenses.
-EVF is not completely ready, but it is funtional in NX10 preproduction model.
-Samsung plans release 2 new lenses in December, one zoom and one fixed. (Samsung we are waiting for camera nowâ€¦)
-NX have been slightly redesigned specially the grip and EVF area
-Wll have a K-mount adapter (AF?, I donÂ´t know) and M-mount, but they wonÂ´t be release with the camera
No picture until nowâ€¦
