Shimano released the new 12 speed mechanical 105 groupset this year, which is Hydraulic disc only. I personally don't think its a good idea to ditch rim brakes when there are hundreds of millions of bikes on the road made of carbon, steel and alloy that can only fit rim brakes. Ultegra and Dura-Ace phased out rim brakes a few years ago.
Tiagra 4700 still comes in rim but its got kinda heavier components. Wouldn't surprise if the next Tiagra is disc-only in a few years. This will leave only Sora and Claris which are low end groups and not high performance.
