SURVIVING SUPERS
You can survive a super like a boss by avoiding, evading or countering a super with another super.
Note that all supers are unblockable, and that the level 3 super is uncounterable (is that a word?).
COMBOS
All characters are very well capable of pulling off extraordinary combos, contrary to popular belief.
They showed videos of examples, and let's just say it was pretty incredible.
RIVALRIES
Each character in the game will have a Rivalry in the Arcade Progression mode. Each pair get a special cinematic cutscene showing how the two interact. The example they showed was Heihachi and Toro. It's pretty neat.
FINAL BOSS
There is a final boss confirmed in the Arcade mode. All they said that, "If you're a fan of Playstation, you'll love it." Gee, I wonder who? *cough*KevinButler*cough*.
GAMEPLAY
Since some people are concerned with the lack of a health, they believe the game is far too bland. In truth, there is sort of a health bar in the game. Essentially, your opponents AP bar is your health bar in reverse. The closer they are to filling it, the more likely you'll die. Superbot has stated that their goal is not to make the game play as close as possible to Super Smash Bros, and that fans should expect pretty much a new unique genre of fighting.
You cannot do 3 level 1 supers with 3 bars of AP. You can only do the super that corresponds to what level you're at.
FORUMS
Superbot has said many times during the panel that they frequently read the message boards. Whoever was worried that Superbot doesn't listen to us, don't be. They also check their twitter apparently.
SOUNDTRACK
The music is said to be incredible. When asked if they planned selling the soundtrack, Omar replied, "If they don't, they should."
DATA COLLECTION TO IMPROVE BALANCING
Apparently, Superbot is able to collect data from online matches and decide what seems fair and unfair. They're able to make fixes without patching.
INFINITE AVOIDANCE SYSTEM
After racking up a certain amount of AP from a combo, the victim will be launched and be in an invincible state. It borrows this idea from Marvel VS Capcom to avoid cheap tactics.
