I'd call the Pentax K20D a close-to-perfect match.
-14.6mp and it does quite well with them, I'd currently call it the highest image-quality APS-C camera
-Most modern cameras can do that if you set the shooting mode to black and white but also RAW, my K20D certainly can...
-In-body SR
-By default you hold the "exposure compensation" button and turn the front dial, but you can customize it to be set directly to the front or back dial in any mode
-Incorporated into the drive modes, which requires only two button presses to access
-You can set the front or back dials to change ISO directly in any mode, there's a dedicated "sensitivity priority" mode where you change ISO like you change aperture in Av, and there's the TAv mode where you set the shutter speed and aperture you want and the camera varies the ISO automatically to fit that, so you don't even have to bother changing it.
-I use it at 1600 all the time in good light and I've gotten away with 3200 under awful stage lighting with a little processing. The camera sets noise reduction to "off" at default to retain more detail, but you can turn it up if you really like to let the camera smear out all the noise (and everything else) like most cameras
-There's a dedicated bracketing button on the left side of the camera, and there are extensive options for the customization of the bracketing. You can even set the order in which it takes the different exposures (dark first, light first, normal first, etc.)
-In the optical viewfinder? Good luck finding that on a consumer or semipro camera. Speaking of which, the VF is second only to the D300 in the semipro bracket. You get gridlines in live view by default
-The LCD is nice and big, it has live view but others on the market have better versions. You can't AF or do much with exposure
-It uses sensor-shake to clean dust off on startup, and if it persists it'll map it out and display the location of the dust on the sensor on the rear LCD to assist in cleaning (reversed so that it corresponds correctly)
-No tilt and swivel, sorry. The K20D is made to be tough and weathersealed and they probably felt that that wasn't going to be durable enough
-Spot metering is easily accessed through a switch on the top
-Auto rotation is a feature
-Cost? I got mine for $650 used, in perfect condition, with 8gb and 4gb sandisk cards. New, you can get them body only for a little over $700. Take that extra $800 and get yourself some nice glass, Pentax has some great stuff.
The Olympus options also have most of these features but imo the pentax offers the best overall value. I am also a longtime Olympus user, just to dispel any notions of bias. The K20D is really more on par with the E-3 than any of the other three, except that it's smaller, doesn't have the tilt-swivel LCD, has higher image quality at all ISOs, and has slower AF and shooting speed.
In short, if you need a speed demon get an E-3 or E-30, if you need something tough and weathersealed get the K20D or E-3, if you want the highest image quality and value and the controls that you asked for above, get the K20D, and if you need the smallest body you can get, get the E-620, though the K20D is also more compact than the other two Olys.
