Probably because of all the electronics they cram in there + the much more massive batteries = bigger cameras.

Digital camera batteries are much smaller than film era batteries. For a start, battery technology has moved on, for a second, digital electronics consume much less power than the motors needed to shift film at high FPS rates. moreover, the stepper motor shutters used now are much more energy efficient than the spring driven ones used formerly.

Edit: realise there is a battery factor here. How many film era motorised cameras could shoot 1000 frames or more on a single charge?
