D800 AF now IMPROVED!

Yes, it works pretty well. You need to practice a bit, but once you get it down it's really fast, easy and very accurate.

Folks need to make sure custom setting 'a4' is set to "AF-ON only" (vs "Shutter/AF-ON"), otherwise you can lose focus occasionally when you depress the shutter. (For some reason people miss or skip that step a lot.)

You can also click it back into af-s pretty quick if you need to enable the AF assist light for a shot or two.

It feels to me like driving a stick vs driving an automatic - harder at first, but then gets very easy and second nature and you don't like going back to the old way. YMMV on how easy/enjoyable it is, but it's effective.
