I mean, he gets a lightsaber through the stomach... it would only make sense that he'd split in half right then and there, I thought it was edited kinda like episode 3 where the DVD shows Anakin fighting grown-up Jedi instead of the children... for moral reasons.
(Does any release of episode 3 have that version, BTW? However, That's one edit I do like, since I almost cried seeing Anakin kill the children and I just hate watching that scene...)
