I don't mean to start anything here Dylan but...
From my point of view, right now you sound exactly like;
- a Halo 1 veteran, before the release of Halo 2
- a Marvel vs. Capcom pro, before the release of Marvel vs. Capcom 2
- a Soul Calibur 2 expert, before the release of Soul Calibur 3 (and even 4)
- a Counter-Strike 1.6 master, before the release of Counter-Strike Source
- a Warcraft 2 battle.net wizard, before the release of Warcraft 3
- and heck, I could even say you resemble a Halo 2 professional, before the release of Halo 3
The list goes on and on as well. I could even make reference to remade movies, games, cartoons, etc...
A lot of the above mentioned people said they would never convert... and for a long while they actually didn't. But in the end, they just made the switch. In a sense, you could even say its Human Nature. Smash Melee is then, and Smash Brawl is now. When Smash Brawl is release, practically the entire tournament scene for Smash Melee will end. You might be able to start a tournament for Melee, but that doesn't mean that anyone will come. Popularity of Smash Brawl will ultimately be Melee's downfall. You won't have any competition, or a large group who would be interested in playing for years to come. I know you are expecting Bam, Vwins, Pkm, and all those people to continue playing Smash Melee, but I wouldn't get your hopes too high, because chances are Montreal will be one of the first places to host a Smash Brawl tournament in Canada.
In my opinion, you also really aren't giving Sakurai and his team the credit they deserve. The developpers of Smash Brawl are players who have 10,000+ hours on all their memory cards. Really I am sure for players that passionate, they wouldn't want to "ruin" Brawl by catering it to casual and newbie players.
Nintendo also plays absolutely no part in the development of Smash Brawl. Sora Ltd. is a third party company. Basically all Nintendo does is shovel Cash into their building, and allow them the rights to the various franchises. Just because of that, we can easily tell that this game will keep it's same action as Smash Melee. Perhaps you don't even notice Dylan, but Smash Melee was one of the few fighters to have the saying "Simple to play, Impossible to Master". Smash Melee was INCREDIBLY Casual/Newbie player friendly. I know tons of totaly scrubs who play this game over any of the other fighters. Smash Brawl and Sakurai will keep that exact same attitude.
I know you'll make the switch Dylan, whether it's sooner or later. It is all about Adapting and Moving on. This is Sakurai's last Smash Bros game, and you can bet your last dollar that he's going to put every ounce of effort and energy he's got into this game.
