Hmm...
So what you say is based on what you have read and what appears to be a jpg test, where you have no knowledge on lenses used etc. and not personal experience?
I have been shooting the sensor (D3) the last year.
Frequently delivering up 60x90cm prints from it, granted my work are all done with either Zeiss or pro line nikkor lenses. I have had no issues with softness from this sensor at any time.
Thus with a year of actual use to speak from, that test you keep pulling up is a joke to me, nothing more nothing less.
How many users do you know of that has stripped the AA filter?
I know quite a number of very satisfied users (most of them depending on it for their living) and none have had AA filters removed, found the sensor soft or anything like that.
Now speaking from a year of professional use myself, I dare say that anyone finding this sensor soft, gotta have either a operator issue, lens issue or a faulty unit. simple as that.
I am not not having any 100% samples online thus unable to post a sample for you, will look into a real world 100% crop for you once I get around to it.
Now granted I do not belong in the pixelpeeping category of photographers, thus I am one of those worrying about tonality, renderings DR and other stuff instead, but I would imagine that either my clients or me myself would have found out if the performance was as poor as described by you, at some point during the last year.
