Here's a summary of everything that was announced this week at the official Smash Bros. blog.
There were several new announcements made over at the official Smash Bros. DOJO!! blog this week. Sadly, none of them were especially earth rattling, but for those of us who are salivating for the release of Brawl, there are a few tidbits to drool over.

Link's final smash was officially revealed, but it had already been shown in the trailer that came out last year. It's called Triforce Slash. One interesting additional piece of info is that the glowing Triforce that appears around Link's opponent actually originates from the back of Link's hand.

Pikachu's final smash was also revealed. It is named after the very rare and very powerful electric attack from the Pokemon universe called Volt Tackle. During this attack, Pikachu can still be controlled, but like the Power Hammer, it is dangerous to move around too much, as made evident in this quote: “It's quite speedy while airborne. This...can be dangerous."

Wario was officially announced as a new character, even though he was also unveiled in the original trailer that came out a year ago. He will be using bodily functions like farting as his primary means of attacking, as this quote suggests: “It's rumored that this unpredictable character will give birth to a form of martial arts that other characters cannot even see."

Two of Fox's special moves were also unveiled, and they seem to be identical to moves that were in Melee. His down special move is the reflector shield that bounces projectile attacks aback at his opponent. His standard special move is a rapid fire blaster that does damage to opponents, but does not cause them to flinch.

Lastly, a new stage was revealed. It's based in the Star Fox universe and is called Lylat Cruise. It appears to be similar to the Venom level from Melee. Combatants battle on the multi-level rear end of a space ship. The ship travels to different environments like asteroid fields and cloudy atmospheres. Players will have to dodge laser fire from incoming Arwings as they battle it out.
That's it for this week's updates. If you want to see them as they go up, make sure you visit SmashBros.com every day.
