I hate to be that guy and make threads like this, but I should say current events don't look like a bright future for the game.
After numerous delays of release date and CBT events (from initial date being set 2011), and a few months of dead silence we get this rather troublesome update that open beta is being delayed for unspecified time:
You may think delays are good for the game quality. Not always. DNF being a good example. I was in every closed beta event and have to say the game almost hasn't progressed at all except a few minor UI updates.
Then we are informed that alpha is going down:
There is no End of Nations link on Petroglyph Forums like it used to be in the past.
Dear developers, if the game is being canceled, tell us now. The sooner you tell us, the better will be for everyone. If there are still plans for release then you should probably interact more with the community and keep your potential customers updated, otherwise you'll see more posts like this.
[Edit] And by saying "keep customers updated" I mean release some new shiny tralers; don't forget about Warfront episodes; do some interviews and question/answers; do some contests; post some interesting polls (most of them are closed right now); in general - keep your community interested.
