An EG-S screen is a huge help for that (something you can't get in the 5D3).
The 5D4 will change that, you will be able to use those AF screens again. The AF screens are still in the 5D3, 70D, 7D, etc. they are just locked behind a frame that has 2 screws in it. You can pull it out and use others, but it isn't as easy as unclasping the screen holder.
Since the 7D informed the 5D3 in some ways, the 7D2 will inform the 5D4.
