Australia's Classification Board has listed a new rating for Sonic Adventure DX: Director's Cut, suggesting that the GameCube game might be ported to current systems.
The rating says "multiplatform," which further vagues up whatever Sega's plans are here. That Gaming Site, which saw the listing earlier today, figures it could be a new control scheme on the Wii, an XBLA release, or part of some new compilation.
Sonic Adventure DX debuted on the Dreamcast in 1998; the Director's Cut was the version brought to GameCube and PC in 2003.
