SilentWolf,
Nah, you aren't rude. There isn't "proof" either way, but the simple comment I was trying to make before the attempt by a couple of posters to beat me to death for even uttering it, which made me defend myself, (sorry, still a little surprised at the immediate reaction I got since I don't post as often as some) is that everything that was in his initial prediction that couldn't be easily tampered with seems to have been satisfied. Given his initial predictions, enough credit is there to suggest that he might have been telling the truth.
He said that both a new and old character would be revealed that week. They were (Diddy and Peach). He said that all but one original character would return. (true if Lucas is replacing Ness and Jigglypuff is announced). He said that all franchises from the last game would return but one. (true if Game and Watch does not get announced). He also said that there were 34 characters in all, 14 new and 20 old. We won't know this until the end.
Now, I don't think his predictions should have as much credit as these posts seem to suggest. I mean, how many characters there are (the only new info) doesn't really matter once we get to play the game or see the next update, but how quick people were to badger me for saying there is enough warrant to keep it in mind was very offensive when I was simply trying to contribute to the board for those who might want to keep updated on the possibility.
People are too quick to judge when someone posts revealing info. Developers and insiders browse the most popular gaming forums all the time. Things like that DO happen despite all the fakes. The only way to know for sure if a person is truly legit is if his predictions come true, and for that we wait.
