ChronoBound, I appreciate your observations, and hopefully people will respect that you haven't meant for something to blow out of preportion like this, but I would also like to say something.
The weight of these claims shouldn't fall completely on your back, especially since you have posted a full explanation of the events surrounding how all of us ended up here, hoping but doubting Roy and Mewtwo's inclusion in the US/PAL release of Brawl. The weight of this should fall on tfox, who at this point has aggravated me to no end - nobody should make such bold claims, especially when examples in the recent past elevated to flame wars and arguments, and then disappear - it really seems that he is avoiding this because he needs time to think of more lies that will explain the initial lies he has made. All we need from him is concrete solid proof that HE was the one that leaked the Advance Wars: Days of Ruin info, and then we can form our opinion based on actual past evidence - not a CLAIM of past evidence. The truth is, that even if does prove he leaked that info, most people will probably still doubt his claims (myself included). Still, he should at least go that far. Like I have already established - tfox's claims and then sudden diappearance, only appearing once, basically, make me believe he's in his basement, browsing this website, and howling in laughter in what an uproar he has caused for "leaking" this false info.
In the end, I really think all of this should be dropped, forgotten. Freaking out over rumored exclusive content is going to make the wait for this game even longer. I know this isn't going to happen, but all of us posting our "theories" on why Mewtwo and Roy could/ should/ won't/ shouldn't/ might be in this game won't cause March 9th to arrive faster. As it stands, none of us know, and none of us will know unless Sakurai or some other Nintendo staff announces it. The best I can muster is that a person with a connection (i.e Serebii, PORTRAITofRUIN, etc.) contact one of their sources and ask if they have heard any info on the possible exclusive/ DLC content.
With this topic, I hope we can just let this die. Brawl will be a good game. There is already a large amount of characters for a fighting game (39 including PT's Pokemon, Sheik, and ZSS), and many levels. If anything else comes of this rumor, great! For now, accept the Japanese Version as basically what we will have. I too hope Mewtwo and Roy will enter the fray, but I still highly doubt the validity of tfox, when all of the evidence has been stacked so highly against him.
