not that it wouldn't be a real one, bit early for copies already, it would just be one of the early samples, (the samples were intended for people to test, not to sell them, oh well) I have mentioned this multiple times but human nature being what it is, well some people just can't wait
in the earlier firmware versions it does work much better with WDR turned off, there has been a lot of improvement since then though and the mass production spec will differ from what you have now but the firmware 'should' be ok for yours and still offer you a good improvement over what you have now, I say should because you'll have a different lens to what the mass production product will ship with and there will be some minor adjustments to suit the new lens
