Actully I checked the website of jp Smash and they're acutlly getting the game on my Birthday.
It's likely they'll use trailer clips and mash them together with gameplay clips, so yeah its going to be brawl all over again.So does anyone think Smash 4 will have an actual intro/opening again? Brawl's was awful, they just stuck together a bunch of random SSE clips and put the main theme over it without any opening-exclusive scenes. I'm optimistic they'll return to a 64/Melee style opening for this game, since there are no SSE cutscenes to lazily draw from this time.
Considering the 3DS is at the forefront with it coming out, we could even get a small presentation on a few of the modes we saw earlier, like the hockey puck thing, the multi-team battle bojangles, all that jazz. I'm not expecting much, but "a few secrets" of whatever makes it seem like we'll get something maybe.
I seriously hope this is sarchasm
