Why do so many people want to see characters be cut? I think most of the cuts from Melee to Brawl made sense (except Mewtwo), as they were just clones that were added to fill the roster. Brawl still had clone-like characters, but I believe each one deserved their spot on the roster. Brawl's roster was amazing. I see no reason to make any cuts from it.
I understand why people think Snake might get cut, but even though I'm not too fond of him being in Smash Bros. (if there was any character from Brawl that I think didn't belong, it would be Snake), I'd hate to see him leave now. His franchise has already been represented in Smash Bros. now, and I'd hate to see the removal of an entire franchise. Besides, Metal Gear is just zany enough to fit in Smash Bros. Snake's secret codec taunts were awesome, and I like how his character was portrayed with some humor.
Also, didn't Sakurai recently say that no cuts have been made at the moment, and that they're striving to include as many characters as possible? Why, then, should we be anticipating cuts? The more, the merrier, after all! If they really want to include as many characters as possible, it'd be silly for them to cut ones that they already have a base for.
