The MP3 standard has become such a reference that no one ever thinks it may still evolve.
The Fraunhofer institute shall announce during CEBIT a news version, the Surround MP3. This new version would bring 5.1 sound support whithout being much bigger in size.
Those MP3 would be compatible with current readers. A few months would be needed to have readers compatible with those new functionalities.
