Watching his future posts for guidance :D
At this point though the 5D IV seems to be too much of a compromise. I still occasionally use the 1D IV over the 5Ds R when I need weather sealing, speed or tracking. The 5D IV may gain on the weather sealing, but with the small battery I would bet it is still gimped on speed and tracking vs the 1 series bodies.
