@Ben - but not all characters do. Some characters will only do one attack if you press and hold A, while some will continue doing the attack. And some characters only continue doing their A attack if they hit someone, then to go into a combo, which you can hold down A to do, like Ike's for instance, but he won't do the combo by holding down A unless he hits someone.
Edit: I'm not saying it's a bug, I guess. It just seems like the way some characters look while holding down A lead me to believe they shouldn't be able to do that. And since not all characters have a "hold down A" continuous attack... but well, it's a pretty hard bug to miss, which was the argument I used with my roommate. I thought I'd bring it up here to see what other people had to say.
