Character development? This should be good.
Quite an awesome update, especially because they snuck Peach in there as well. Also note how it explains that weird update from a while back, so now I can rest easy.
As for Ike, it's possible that he's a replacement for Marth, but it's more likely that he's taking Roy's place. I'm pretty sure Roy was only added to Melee to pimp the then-upcoming Fire Emblem GBA game, after all. As long as there's still a character that plays like Marth I don't care either way.
*E* What the hell? Apparently Eji Aonuma (Current producer of the Zelda series) has
confirmed Ganondorf...and Sheik for Brawl. Ganondorf was kind of a given, but Sheik is unexpected (And weird). Mini-Megaton?
