WHAT? NO! The Subspace Emissary cutscenes were one of the best parts of Brawl! They were so awesome and the great invasion remains one of the best moments in ANY Nintendo game!!! You can't just get rid of the cutscenes, you can take away the terrible platforming or maybe make it have more to do with the universes that these characters come from.
And the YouTube excuse, I'm not buying it, if someone gets the cutscenes spoiled for themselves, that was THEIR choice! Allow people to spoil it for themselves if they want to, and respect that there are also many, many, MANY others like myself that deliberately try not to be spoiled!!
And if someone spoils the cutscenes for themselves, they aren't going to go "well now there's no point in buying the game". Everyone buys a Smash Bros. game for the multiplayer!
Sakurai has said some worrying things about this game so far, there won't be a larger number of characters, there won't be any version-exclusive characters, there won't be any 3rd party characters (other than Mega Man). It's just not sounding good, every Smash Bros. game has got BIGGER, this actually sounds like they're taking a giant leap backwards.
And about the platforming in SSE, it was very obvious that the level design was very Kirby-inspired, but the characters were not made for platforming!
