The Smash Bros. Brawl website has been keeping true to its promise of daily updates. Since the Final Smash post, the blog has shown a new map (Delfino Plaza), a new weapon (the unfortunately-named Cracker Launcher) and the ability to now move while shooting.
One interesting note in the description of the Cracker Launcher, essentially a Roman candle, is how you can "aim the launcher at different angles by tilting the Control Stick up or down." The mention of the control stick sounds like a reaffirmation of series creator Masahiro Sakurai's statement at the game's unveiling to keep the game compatible with GameCube controllers -- then again, it could also be a reference to the joystick on the Nunchuk attachment.
The constant stream of a news, coupled with earlier comments from Hideo Kojima, indicate that the game is coming along well. Here's hoping we'll get a release date (and some hands-on impressions) at Min-E3.
