I may add some technical details:
All the three versions (MorphOS, AmigaOS 3, AmigaOS 4) of DigiBooster 3 are developed synchronously, so all will be released at the same time.
DigiBooster 3 still uses the same module format (known as DBM0, or *.dbm) as DigiBooster Pro 2.x, so of course DigiRoller plays DigiBooster Pro 2.x modules too.
