There have been rumors abounding that Nikon has purchased from Samsung the infrastructure behind the NX line of Samsung cameras. We have no confirmation as of yet and we will be surprised to find out if this is true. Stranger things have happened though. We will keep you posted.
We were very sad to see Samsung fold as their NX1 produced great 4K video (even sharper than the Panasonic GH4) and the firmware updates were frequent from Samsung. Sony needs some serious competition to their mirrorless cameras.
