I did not actually post what I meant to before, haha.

What is the point of the videos?
- Garnish hype for newcomers
- Introduce newcomers to those who are unaware of their origins
- Show Nintendo characters among other Nintendo charaters
Two out of three of those proves that characters such as Isaac, King K. Rool, Mewtwo, Ridley, etc, do not need videos, and that introduction videos (as they are called) are in fact useless.
Sure, it is fun to see them alongside other Nintendo veterans, but perhaps we will get to in another mode in the Wii U, or even the 3DS, as Sakurai said he was keen on these interactions.
We all know who these characters are, they've even all been in Smash bros before.
A character who has been in the series' before and is not making their debut does not even have much business having a video.
This is, of course, debunked by Palutena, who appeared in Subspace Emissary and Pit's Final Smash, but the notion is still pretty strong, I feel, that the videos are to garnish hype and introduce characters, which is again a restating of the characters we are GETTING unlocked, from the start, are the ones we are being shown now, and the ones who don't need hype, need no introduction, will make you scream to fight later in game and who you tortured yourself over not knowing if they were in the game- they are the locked characters in the game.
It just makes too much sense given the amount of appeal Sakurai puts into wanting to surprise his fans, but also cater to them.
