I'm not holding Halo up as the holy grail of video games. And it currently holds the record for day one entertainment sales (not all-time sales)--that includes movies, computer games, etc.
Also, Halo 3 is not "more of the same". It's just as different and genre-defying as smash brothers, and I'm willing to bet the scripting is far more complex.
Sure, be happy there's any info at all. I'm saying that what's happening in Smash Brawl is evidence that Sakurai and Nintendo aren't able to keep up with Xbox--at least in America--if they keep going the way they are. Halo has changed just as, if not more, drastically than smash. And yet, they manage to take 10-12 minutes out of their day two or three times a week to bring new information. It doesn't matter whether Halo is overrated (personal opinion), whether it's simpler (it isn't), or whether it will sell well when it's released (it will). What matters is that Bungie and Xbox live have proven themselves to be reliable, dedicated to their fans on a personal level, and working hard to create a great game and have the fans be a part of the process through the whole creation of Halo 3. Even if you hate the Halo series, the amount of care they put into informing their fans should be evident.
Sakurai, however, has shown that most of his concern is for Japanese gamers, that he's not too terribly concerned with releasing information as the game is created, and that he's not particularly dedicated to fans. It doesn't mean that smash won't be an incredible game (it will), it just seems to show that he's not too concerned. The surprise announcement of Halo's release date was reported in major newspapers across America. Smash Brawl has barely hit IGN's mainpage.
This is a new era of video gaming. Gamers need to be informed. PS3 successfully alienated all of its gamers, and Sakurai's right behind them. You can be happy with what you've seen if you like. I think we should get more... the relationship between the fan and the creator should be a lot closer than it is now.
