Thats right, just to make it simple, i wrote down things on the sight (www.smashbros.com) that waa either in the picture, OR in the text. 0% of these could be right... doubt it though.

CHARACTER PAGES
Pit
Wings of Icarus- This either flies around freely then shuts deactivates, or pit simply gets less and less lift overtime.

Wario
The "hog" appears to be an item...
Wario Waft may be used to recover... (sends him up a bit in the picture)

Mario
in the final smash caption...(BambambambambamBAM!) the last bam in caps implies his final blow may be heavy...

Kirby
"The only character whose apppearance hasn't changed from melee". This implies that all characters will either:
Make it into Brawl
Look different than Melee versions.

Fox
Reflector- "take it out to initiate" this implies it is NOT instant anymore.

Bowser
lots of characters get "new flavor"... "if you thought they would all be the same..."
wait. they ALL? this implies all will make it again.
GigaKoops may be too big to make flinch = holy %$&#.

"You must recover!"
Mario makes an amazing comeback...

"Smash Attack"
Picture hints players won't flash yellow when charging...

"Standard Combos"
"others may do 3 slow swipes with a blade" Does this hint Ganondorf?

"4 kinds of control"
this text implies Brawl will have Rumble...

Delfino Plaza
Bowser Jr. ? (Each stage gets character logic is implied)
Lylat Cruise
Wolfen seen in backround during World Trailer. This implies Wolf... sorta...

Bridge of Eldin
Bulbin in video looks like it was gonna kamikaze the bomb...

Smashville
Slider makes same exact entrance as Trailer 1 newcomers... K.K.Slider is implied here... ?

Gooey Bomb
seemed to stun characters when transferred... (anyone smell a free smash attack coming?)

Barrels
wee... can stand on em. whoopee...

(What are ATs?)
in nintendog pic, Mario is awefully low... revealing what could be a super giant stage...

S. Goroh
runs while swinging.

Dr. Wright
possible temporary platform?
