I dont hope that. After all they did make a very good box (hardware). If they go out of business it will mean that the production stoppes. And with less boxes made, there will be less users, and thereby less support from third party developers and user forums and so on.
The best thing that could happen, is that E2 gets 100% ready, and OpenSat makes a deal with the team to have E2 as their standard firmware. This way both can make profit on this.
