I think this will be a different style of event than most people are expecting. It's not speedball, but it's not hardcore milsim either. Think like the games that go on in the background at the Summer Slaughter events, just on a larger scale. This wont be one game running all day, it will be more like a few hours at a time and then rotating groups between a wooded and a town field. There won't be a lot of need for extensive preplanning like the MSW events, this won't be that kind of game.
I've been working with PWG on this for a few months. They are new to airsoft events, but they want to put on a really awesome game and they have the resources to make for a really impressive experience. There will probably be some bumps in the road, since it's a new operation overall but if this first one goes well enough you can expect that there will be more in the future.
