Well it does need an OS ported to it first and if it was originally their intention to use the Sonnet Crescendo they will no doubt have to change their plan at this stage and design a new card.
According to their reply to user at amigaworld they are doing just that.
linkI think I read some months ago that another user pressing them for information was told that they were/would be working Hyperion to get OS4 ported. Rogue used to be pretty quick to deny that Hyperion had received a SharkPPC* from Elbox so who knows, though of course he may just have missed it.
It might also make the Dragon a worthwile upgrade too as that has AGP and from what I can see on board IDE.
Anyhow as always in the Amiga game it's a case of wait and see, or perhaps beter forget and be pleasantly surprised
if it does appear.
*Elbox never claimed to have sent a SharkPPC to Hyperion, Rogue was just replying to speculation on the forums.
