ED is very plainly advertising these testing builds as testing builds and not "the next big thing you should totally get simple customer."
However the community doesn't feel that way. The strong impression I get of the fanbase is one of a collecting instinct. While other game sim fans are discussing tactics, meetups, grouping, and other such use of the content DCS fans seem unnaturally preoccupied with acquiring the next thing shortly ahead of the "can I ramp start this" tick box checking. I feel that if no more content were released from DCS it would lose a huge quantity of fans. The present content, however enjoyable it is, doesn't seem to be what they're after. As such novelty is in prime demand.
