Yes but, downsizing an image negates any resolution advantage that you have from the higher rez sensor. At any rate, I hope the per pixel noise performance of the 7D is as good as the 1D3, if not better.
On the other hand, if you intend to print the same size final output, it doesn't hurt to compare two images at the same pixel resolution. Unless, of course, that final print might be compromised by the resolution of the lessor of the two bodies being compared. In that case, it would be better to uprez the lessor image to compare.
I don't think that the per-pixel noise from the 7D will be as good as that of the 1D3. But I do think that an 18 mpx product gives you some options that the 10 mpx image may not.
I'm really anxious to see if this new camera has some latitude with which to work. I found that my 40D images, if properly exposed, were quite nice. But the 40D images shot at ISO 400 and up did not hold up as well to raising underexposed shadows when compared to the 5D.
