If the ESC is made with enough FETs, the resistance is lowered and power dissipation will be lowered as well resulting in less heat. Also, there seems to be some evidence that Castles has quite low pulse rise time, further lowering heat dissipation. If done right, a heatsink shouldn't be required, although I'd still put one on there for peace of mind. Plus, you KNOW people will be pushing the ESCs beyond their intended uses...
