The view is complicated by that the 60 isn't perfect either. It shows both tiling and ripple. The tiling part differs quite much between different sensors instances and digital back calibrations, and the color cast can vary a little bit too. Tiling and ripple cleans up quite well though, and AFAIK it has become even better with later versions of C1. With high contrast processing, as often used in B&W the tiling and ripple can still re-appear in some circumstances. The individual variations in color cast has no effect, it's cancelled out in full by the individual LCC.
AFAIK for color photos with normal contrast the tiling and ripple should never(?) be any problem for the 60. It was a little for the 80 in the older C1 versions, but it seems it has improved (haven't tested myself).
This leaves the desaturation/crosstalk issue for large shifts to be the only relevant difference left, which obviously is not much of an issue for B&W processing. For the lazy ones that doesn't want to look into trond's test shots above, here's an example of how the desaturation can look:

for an IQ180/ SK60XL
as most colors in nature are relatively desaturated to start with rarely bad things happen when there is crosstalk, they're just further desaturated. If you have a high saturation color you can get color shifts too though. If you ask me the desaturation is pretty clear at 15mm shift on the 60XL, and to me that level is not really acceptable -- the colors are not unlike what I get from my mobile phone camera in low light (dull brownish pastel) and that is not what I want from a system at this level. I'm not that worried about a shifted lens getting a bit blurrier as it's a pixel peep thing, but the color degradation is not. However, if you see it as a sort of "vignetting" creative effect you could accept it, and in any case few would notice. I guess you could patch it with some manual post-processing tricks too.
It all comes down to taste and needs in the end which varies between us all. I would keep the IQ260, and I don't even like that due to that it still exhibits those tiling/ripple artifacts, even if I can clean it up with an algorithm (and I spent lots of time making one as good as C1, or even better than that at the time at least) I just don't like a sensor being dependent on that type of cleaning, so I'm still on this old-school Kodak and will probably stay there until doomsday but then I've had to give up other things like top notch DR and resolution. Well, if I had loved Rodenstock Digarons I'd probably go for a Dalsa anyway -- then the 60MP -- so I actually got to use my tiling/ripple cleanup code
, but I'm into the Schneider Digitar wides (due to distortion-free, lower weight and more traditional large-format style design) and as we know those don't play that well even with the 60.
