Canon acknowledges, doesn't fix black dot and band problems on 5D Mark II

It's been released, unboxed, and adored by many. But, like other eagerly anticipated bodies from Canon, the 5D Mark II hasn't been entirely trouble-free for the early adopters. The company is at least stepping forward and confirming that the new model's two most commonly reported problems do indeed exist -- but isn't going so far as to fix them just yet. The first issue is called the "Black dot" phenomenon, where bright point light sources (like streetlights at a distance) result in a grouping of dark pixels immediately to their right, as seen above. The second issue is ugly vertical banding, apparently appearing only in sRAW1 mode. Canon has no advice on the first problem, but says you can avoid the other one simply by not shooting in sRAW1. Surely millions of photogs are wondering why they didn't think of that.
