Soooo is it disc brakes or what? Tesla's move to unboxed model means they won't be able to have hydraulic lines. 48V means more power, but still need something

Soooo is it disc brakes or what? Tesla's move to unboxed model means they won't be able to have hydraulic lines. 48V means more power, but still need something like 50A per brake disc, IMO non starter for Tesla. Is it going to be batteries/supercapacitors or some other novel brake design.
