(((Note* Still updating lots of info)))
WELCOME SSB FANS! This thread i made a huge list of hidden things from the direct, including unnoticeable changes like New Moves, Hidden Gems, Etc.... So I hope you can enjoy and take it upon yourselves to look up things i listed! (Took awhile to do o.O)
(Yes its trivia and there will be more info as well in the second post)
IMPORTANT⇒ This is the video of the SSB Direct: http://www.youtube.com/watch?v=7xUWnQu2Grs
Every thing shown below with a time listed will appear in the trailer, Ex: [12:15] says ........ Then look up the trailer at that time and see it in motion!
Well Lets Begin 
⇒Did you know that every time a person dies, the character that finished them will be surrounded by a color light from now on? [1:59] has Samus glowing Red and [15:44] has the character glowing Blue. My guess is wat character (player 1, player 2, etc) does it corresponds with a specific color
★ Stages
~Balloon Fight (3DS) [4:48] This stage is unique as their is a huge gimmick not seen before in any SSB stage before. Looking at the video you can see a character can run from one end of the screen and instead of dying reappears on the opposite side!!! Look at Peach+Samus do this at [4:48]!
~ Gerudo Valley (3DS) [4:14] Bridge is broken from Atks. Also small platforms exist on both sides for safety before falling in the pit. (Also some weird ice platform on the right inside the waterfall)
*Not Confirmed but it appears Ice will be a hazard on the right side of the stage while fire on the left (from the witches in OoT)
~Arena Ferox has at least 4 different playable set ups including a basic floor like Final Destination
Many many changes has happened with Bowser! Including hisnew stance and faster movements. Check it out!
[2:03] Bowsers New Forward Air
[2:05] New Up Smash (Does a Triwl while jumping) *might just be animation thats new
[5:03] Bowser has a new "A Combo". He jabs twice now!
[6:43] New Up Air (or Neutral Air) is a new atk thatmakes his body spin aand has a Huge range of a hitbox! O.o
[6:59] Bowser's Down Air shoots very very FAST now!!!!
Next up Princess Peach!
[2:01] and [2:46] Her Side Special is MUCH FASTER in activating! (previously small lag)
~Below pic shows cosmetic change to her Up Smash
Aside from cosmetic appearance and obvious moveset upgrade, she gets a new Forward Smash Atk [22:35]. She now does a kick followed up but a far kick!
Charizard Has Some great changes!
Mega Charizard X will most likely be a Final Smash
[38:35] New Forward Air
[38:37] New Side Special (im guessing its flare blitz)
Unknown move for his B down as pokemon trainer doesn't exist!
Many of his moves stay the same but look to have added some tweeks into them!
[23:13] Yoshi's back air now hits very hard at the end of the atk (knockback is now there)
[23:19] Down Air now pushes back opponents when its finished!
[32:20] New Dash Atk!!!!!
[35:09] FINALLY has his Roll Atk (new dash atk)
[8:18] DK Up Special is exactly the same airborne.... BUT is slightly different when used on the ground. On the ground he's angled while swinging!
[22:36] Link now dodges with a backflip like in OoT and has a new dash atk
[28:05] Villagers Loid Rocket (Side Special) can be rode on if used in the air. While on ground Villager just shoots it
[28:21] Not sure but to me it looks like the wooden parts shoot out like a projectile (must see)
