Completely agree. I'm hoping it's something similar to Gran Turismo 5 where they update contents for free on the console, except that this time, the game is complete and they update when they think of something/cater to fan's idea to expand the game. This wouldn't mean free characters/stages (Although that would be amazing), but it would improve the game for years to come.Ahhhh, I see where you're coming from. I like this idea as it would expand the gameplay in other ways then Special Moves. Basically giving us five Special Moves not including Final Smash.Now I see where you're coming from, but I still don't see why Mewtwo would be replaced by Pokemon Trainer. They are completely different with each other and based off Lucario's moveset, it only makes sense that he's the replacement for Mewtwo for Brawl and maybe SSB4 as well.
The second paragraph I quoted also ties into my theory that at least one of the characters planned for Brawl will be in SSB4. There are five/six characters planned for Brawl that did not make it: Dr. Mario (Possibly an alternate costume instead for Mario), Roy, Mewtwo, the suggested Minun and Plusle character, Dixie Kong, and Toon Zelda & Sheik. Of those, Dixie Kong and Mewtwo are the most likely to be playable in SSB4, thought the chances of both getting in are questionable at best.
