35 character roster is absolute bullcrap.
1. Melee was rushed, yet it managed to include double the amount of characters that Smash 64 had.
2. Brawl has more than DOUBLE the development time than Melee had.
3. Brawl has a MUCH BIGGER team working on it than Melee had.
4. Brawl has been DELAYED, TWICE!
5. The Smash Bros series is starting to become one of the most important series for Nintendo.
6. Sakurai and various other Nintendo reps have stated again and again that the amount of content in Brawl is insane. And judging by the trophies, stickers, assist trophies, pokeballs, past stages, the amount of starting characters... it's quite obvious that there will be plenty unlockables.
7. And last but not least, it's a fact that the characters are the selling point in the Smash Bros series. That's what the game is all about, seeing all those well known figures and getting that nostalgic feeling.
When you take all these points into consideration, you'll see that a 35 character roster would be INCREDIBLY STUPID, and would most likely disappoint a lot of people.
I honestly doubt Nintendo is stupid enough to oversee these things. I'm sure they're including plenty of characters, perhaps even more than we are expecting.... at least, that's what they're constantly hinting at.
And do you think they want to create false hope? Yeah, me neither.
