For what it's worth... I bought a Tiffen 3-stop ND filter a couple years ago for my Tokina 19-35, but I've yet to use it... maybe now I will

That is exactly what I was thinking as well...
Anyway.
One thing I'm looking forward to with the K10D is doing panoramas. The files not being too large, and the CCD output, should make for wonderfully rich panoramas. Converting to .tiff is a bit of a pain when working with Microsoft ICE, which doesn't accept .DNG files (or .PEF). But I think it will be worth it.
I've even done a little "guide" for what kind of DOF experience I will get (basically for Brenizer style panoramas):
Panorama vs sensor size (1/3 image overlap)
pano of 4 (2x2) = 3 times area. Factor = 1.7 APSC/1.1 FF
pano of 9 (3x3) = 6 times area. Factor = 2.45 APSC/1.6 FF
pano of 15 (5x3) = 10 times area. Factor = 3.2 APSC/1.79 FF (same for pano of 16 4x4)
pano of 24 (4x6) = 14 times area. Factor = 3.74 APSC/2.43 FF
pano of 25 (5x5) = 15 times area. Factor = 3.87 APSC/2.51 FF
Equivalence
FF=1.5xAPSC
645D=1.3FF
645=1.77FF
6x7=2.2FF
Of course this is not an exact science, results will vary as much as 20% I think. But it's a good guide.
