I won't say anything bad about PeachyHime's tweet or whatever. She's entitled to her opinion, but I think we should all wait for the game to come out before we completely condemn it like that. I remember going to one of the early Brawl tournaments before the game was released, up in Worcester, MA. When I finally got on one of the setups there was some insane input lag and the whole game controlled horribly, but when I got the actual game it had none of that input lag at all.
Now that I think of it, that particular tournament was 1v1 with items. I know it wasn't as publicized as the Invitational, but I have to wonder why they didn't just do 1v1 there too. Other than the obvious 'we designed for 4 players!' there was more than enough 4 player footage throughout E3....Ah well
