Matthijs,
Ok, not being available yet explains a lot. Begin May, the card was already listed as 'available' at Thomann, then halfway May they mentioned 'delivery date 23rd of May', which made me conclude it is available already. But today their delivery date is listed as the 8th of July, so we'll have to wait a little longer...
The ADI8QS arrived one year late, so that's nothing. I'd rather have a 100% stable device than the usual rubbish.
I assume they didn't release the programmers documentation yet?
No, it will be available with the card. But pretty soon afterwards you can expect driver support, if it is not a completely different design (which was none of the cards so far, just small differences, since they are all based on their pretty stable FPGA design).
