This has been a really unpredictable week, but nonetheless I'll go ahead and make a prediction before I leave. >_>
Update types so far:
November 5th - Story mode, music
November 6th - Item
November 7th - Assist trophy, how to play
November 8th - Special moves
Unused: Character profile, final smash, stage, Poke Ball, game mode
Expectation: It'll be one of the unused update types.
November 5th - Double update
November 6th - Single update
November 7th - Double update
November 8th - Single update
Expectation: It'll be a double update in accordance with
teh pattern.
Previous Fridays that fit into the types of character profile, final smash, stage, Poke Ball, or game mode:
Character profile - Pit, Samus, Peach, Ice Climbers, Snake
Final smash - Peach
Stage - Delfino Plaza, Lylat Cruise, Bridge of Eldin, Smashville, Wario Ware
Poke Ball - Never on a Friday
Game mode - Four Kinds of Control, Tourney, Taking Snapshots
Expectation: The double update will be a character profile and a stage.
Fact: We've never had the same series get two stage updates.
Fact: The only series without stage updates are F-Zero, Metroid, Sonic, symbol 13, and symbol 19.
Expectation: A character who came with a stage from the same series could only be from one of the series without stage updates.
Final Prediction: The character will be from F-Zero, he will be Captain Falcon, and the stage will be Fire Field. Time for the triumphant return of The Knee.
Edit: I also wouldn't put it past them to go ahead and give us Ness on Friday despite the frenzy for tonight. I mean, Zero Suit Samus showed up the day after Samus' final smash.
