Smash 3DS Unlockable Pattern

[3D Dillon]

Recently I've noticed a pattern for unlockable characters in the Smash games.
Take a looksee:

In the 1st game, only one character (Luigi) is unlocked in a way aside from clearing 1P Mode.

During the 2nd game (Melee), when I was a kid, I had the most trouble unlocking the last two characters (Mewtwo and Mr. Game & Watch).

The 3rd game (Brawl) had three characters (Jigglypuff, Toon Link, and Wolf) who can only be unlocked after clearing Subspace Emissary.

In the 4th one (3DS version), only 4 of the 12 unlockable characters are newcomers (Bowser Jr., Dark Pit, Duck Hunt, and Lucina).

Finally, it has been rumored that the 5th release (Wii U) would feature five more unlockable characters (Ridley, Mewtwo, Dixie Kong, Choir Kids, and Impa).

Get the pattern?

Who would have guessed?

I don't see how this is a pattern at all?
