Your favorite levels from Melee may still show up in the new Smash Bros.
The newest update to the official Smash Bros. DOJO!! blog is short but sweet, confirming after much speculation that "a number" of stages from the previous game, Super Smash Bros. Melee, will be included in Brawl. The only one shown so far is Temple, the massive stage set in Hyrule with upper platforms and underground tunnels. New screenshots depict new characters like Wario and Diddy Kong chasing each other through this popular battlefield.
From how this update is structured, it looks like more classic stages may be revealed in future blog posts. Also, Sakurai-san notes that the stages may have slight differences in geometry and even background music. For instance, the Temple stage has a new song remixed from Zelda II: Adventure of Link, and it can be heard at the link above.
