>> The audio driver for Tabor [...] is A-Eon's duty

From last year's AmiWest:

"What's missing before the board can be released is the audio driver and a finalised AmigaOS 4 ISO containing said driver. Dickinson could not describe the audio driver's current status since an update from the developer working on it didn't reach him in time for the show."

To me, this doesn't read like Hyperion is the developer, even if the developer commissioned by A-Eon may have (had) ties with Hyperion.
