According to a recent ratings entry at the Australian classifications board the OFLC it looks like we could be getting a new port/remake of the Sonic Adventure Gamecube/PC port Sonic Adventure DX: Director’s Cut. All we know right now is this new entry was rated on the 18th August 2009 as ‘G General’ and will be multi-platform.
The original port basically added some glossy changes to character models, a mission mode and all 12 Sonic Game Gear games. There’s no limit to what a new version on current consoles could add to the game if Sonic Team really worked at it.
We’ll be keeping an eye out for any future info/media on this, so stay tuned.
