Michael Boehmer of E3B told me there cannot be another run of Deneb because he and Chris Hodges have fallen out over something.
I don't know the details (and I don't want to, it is a personal matter and should stay between them), I've talked to both guys over the years and both are really nice people so I'm sure it must be something they cannot get past.
The result is that Michael can no longer license Poseidon. Without a software stack he cannot sell Deneb.
As we all know, "Silicon without software is just sand" and so Deneb is gone
