considering the anime is finally reaching this awesome fight i thought i'd pose this interesting question. If the sound/sand hadnt interrupted the tournament for their attack and the fight had continued on as normal, who would have eventually won?

Sasuske was kickin ass to begin with. With lee's speed and taijutsu combined with his own sharingan and chidori he had plenty of advantages over gaara's sand defenses.

but even so, beating gaara that way only pushes him closer to unleashing the demon trapped within in. Unlike naruto, sasuke wouldnt have any hope of beating gaara at that point because theres just no way he could compare to a demon.

Of course, this brings up another point.. Would gaara get disqualified at that point for bringing out his demon? I'd imagine he wouldnt do so in a controllable manner as naruto did with the kyuubi chakra during his fight with neji. With gaara it'd probably turn into some massacre as he killed everyone in attendance at the stadium. Thats just GOTTA be against the rules somehow
