Matt Higby talks classes...or not?

A big breakdown of what to expect and not to expect from Planetside 2, all in an interview today at Gamebreaker.TV. He has no date of when the anticipated beta is starting, but he does talk classes, back-capturing points, long term goals, and additional islands or continents. There's good stuff here but I'm stuck wondering what Planetside 2 can do to beat out against DUST 514.
