I'm interested in this, but it has all come about so fast that I'm a little skeptical..
The private server thing I'm thinking would be a direct reaction to alot of people wanting that feature in DayZ at the moment and not being able to, or knowing if they ever will.
Alot of the content they claim and hopefully will deliver is interesting, I'm looking forward to a more coop friendly non-linear world. I signed up for beta awhile ago but havn't heard back yet.
Alot of pressure on these guys now and it will be interesting to see it develop more.
