It is very unlikely that's why there's so much controversy and the ridiculous assumptions that characters like that can make an appearance in brawl at all. People really have to take into account what the characters really have going for them in terms of their links with Nintendo (if they're 3rd part) I.E. Every single sonic game (aside from Sonic next gen) since Dreamcast's downfall has been on a nintendo system. The companies have good relations with each other (not only that but people have been waiting for the Mario vs. Sonic battle for decades).
In the case of Konami, Kojima actually begged Sakurai to allow Snake into brawl, and I personally still think he's the most out of place character EVER.
Of course, people can't believe that every character that there is a support thread for will get into Brawl, that said, I doubt that most people believe that these unusual third party characters have been chosen for Brawl. It would be a welcome surprise, but highly unlikely in their opinion.
Not only that, but tons of people (myself included) were sure that Megaman would have the 3rd Third party character slot. Capcom and Nintendo have been pretty well with each other (although more Resi games and some of the Megaman X sequals weren't released for Nintnedo consoles) however that evidence alone may indeed be why Sakurai never contacted Capcom about allowing Megaman into the brawl. (There's a deconformation in the General brawl section. an article, I read it yesterday) howeverin this case there is still some time (about a month) for Sakurai to give capcom a ring and say (hm... We need a new third party character. Can Megaman be in Brawr?) though it still seems unlikely with the amount of time left.
Certainly, this sort of thing does happen, though it is possible that people are just keeping their lips locked about it so as not to spoil.
Now here's something I can't stand. Square character supports. Square and Nintendo are fighting tooth and nail against each other for the RPG world. There's no way in hell that Sora, Cloud or even Dante (although he's capcom too but has never appreared on a nintendo system in his own game) would be put into brawl. Because Square and Nintendo are bitter rivals!
Hmmm, square? Square used to be on extremely bad terms with Nintendo because Nintendo refused to switch to disks when they were developing FFVII, so they ended up moving over to Sony and being a Sony-only company for a while.
However they patched things up recently, according to some statements they're gonna start making original numbered FF versions for Nintendo's console as well as Sony's (granted, this was prior to the wii), and they've been doing tons of side-stories and ports for Nintendo consoles, as well as the sequal to one game that wasn't numbered but was enough of a classic that it's name recognition made it so it might as well have been.
Nintendo and Square are no worse off together then your average third-party relationship.
I think you mean Nintendo and SONY, though really Sony doesn't have a whole lot of important first-party characters anyway (and I have yet to see a "Dart (The Legend of the Dragoon, look for it, awesome PSone game) for Brawl" thread.
So yeah, I believe you thought that Square was first party for PS yet still did all it's rpgs. That's not the case, Sony is another, popular, but random third party company that Sony is depending on to drive it's playstation consoles foreward.
Square and Nintendo are not in direct competition for the RPG World, but as one of the most influential rpg companies (especially now with Enix and Square being merged), SONY and Nintendo are in direct conflict to work with Square.
Actually the case for Sora is stronger then Dante because Sora appeared in Chain of Memories, a GBA game, and will appear in an upcoming DS game, whereas Dante never appeared on a Nintendo System.
But still, there is a POSSIBILITY for even characters like Dart (even though Hell would freeze over and the apocalypse would occur before Sony would let it occur), so it's not fair to not let people dream about the possibility, of him or characters who are less close to impossible.
If that seemed like a disagreement, it wasn't supposed to... I'm agreeing with you... in a completely unusual way and giving more evidence to that fact.
Well, something you said caused a disagreement, so it's all good.
