I am curious to know if the new 5D Mark II shows horizontal banding at high ISOs (6400 and over) like most of the other models of Canon I have bought in the past. Anyone have any experience with this happening?

There was a vertical banding issue, but the latest firmware was to address that along with another issue.

It improves and mitigates the following image quality phenomena.

1. "Black dot" phenomenon (the right side of point light sources becomes black)

When shooting night scenes, the right side of point light sources (such as lights from building windows) may become black. The phenomenon may become visible if the images are enlarged to 100% or greater on a monitor or if extremely large prints of the images are made. This firmware improves and mitigates this phenomenon.
2. Vertical banding noise

If the recording format is set to sRAW1, vertical banding noise may become visible depending on the camera settings, subject, and background. The firmware improves and mitigates this phenomenon.

I think the firmware addressed what looked sort of like interference banding or something like that. There were some samples on dpr.

As for the typical high-ISO banding. ISO6400 seems to be pretty clean, but I'm sure it would show up in an underexposed shot. In most conditions, high ISO banding is noticeable at ISO12800, and very noticeable at 25600.
