I am quite sure they will be around a long time.
The Beowulf has a large following with waiting list for complete rifles as well as Uppers and lowers. I waited 4 months for my lower to come in, I just got it recently which allowed me to complete my build that I have been working on for the last 6 months. I am sure it will be around for a long time. The ammo is expensive for these rifles but since I reload and components are not too difficult to find I have built up a decent stock pile.
Here are a few pics of mine....
