For me I will get new MK3 with great discount price !



I think the biggest deal about the new 1D MkIV is the low light sensitivity (Vincent Laforet's video is impressive) - unparalleled by any other Canon camera (although it will be interesting to see if the claim holds true once we see some test shots). If someone is primarily a daytime outdoor shooter,you're right, they're likely just fine sticking with the 1D MkIII (unless of course increased resolution or video are important to their workflow, but if that were the case then the 5D MkII would likely be a better fit for the job, so long as burst rate can be sacrificed and AF is satisfactory). But for a lot of people who shoot indoors (or even outdoors in low light conditions, e.g. high school football game) with horrible lighting the MkIV is likely to be incredibly valuable. And with 16MP you could possibly afford to shoot with a shorter wider lens and crop to a comparative 10MP image which is usually plenty big enough for most uses. I'm already thinking that for gymnasium sports I'll have my 70-200mm f/2.8L IS on the the new 1D MkIV and my 50mm f/1.2L II (or 24mm f/1.4L II) on my 'old' (1 month) 1D MkIII. While not as impressive of an evolution as I had hoped, still impressed none the less.
