Factor 5 just recently posted the specifications for MusyX for GBA on their website.

Word on the block is that the sound system for GBA is significantly better than the sound system for GB or GBC, and equals or exceeds that of the SNES. How does 32 channels, and built-in Dolby Surround (with headphones) grab you? Unless Nintendo includes some killer speakers with the GBA, it looks as though playing with headphones on will be the only way to fly (not that your parents would mind!)
