You all need to work on your reading comprehension.
The interviewer whined about "no items" and the like, but Sakurai only said that they (the developers) messed up. He mentioned the limitations of the system's online model (probably about the input lag and the Wii's lack of ability to patch the game post-release, maybe the matchmaking system) and the fact that you can't play in a variety of ways, and he's right.
He's not lamenting people's lack of item play--He's talking about the overcentralizing defensive mechanics and burst range options, which are (or potentially are, depending on who you ask) a problem offline, but the issue is made significantly worse by the netcode (where even with a perfect connection, you have at least six frames of input lag, and usually much more than that). He means that the only way to reliably compete online is by not approaching, and that players can't use any other strategy, such as strong offensive pressure, because any other strategy is tantamount to making sure you lose while online.
I commend him for being able to acknowledge that they messed up, and it gives me hope for the next game.
